I try to get last row index in Excel file using apache poi but getLastRowNum() always returns wrong number of rows and the number is always 1048575 .
My xlsx is simple. It has only three rows with content.
Here is the relevant code snippet:
Sheet sheet = workbook.getSheetAt(0);
int rowNum = sheet.getLastRowNum();
log.info("LastRowNum " + rowNum);
Apache POI version:
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>5.2.2</version>
</dependency>
OS: "Arch Linux"
JAVA Version:

I try upgrading apache poi but this doesn't fix the things.

Integer.compare was introduced in Java 7 and you're clearly using Java 6 based on the error message.
Try using Java 7 or Java 8.
I'm having a problem selecting data from Informix database tables using python3.5 and pyodbc/unixODBC.
I have a little py file (ifx.py) the contents of which are:
import pyodbc
db=pyodbc.connect('DSN=Test1')
db.execute("SELECT * FROM customer ")
and I get an error :
pyodbc.Error: ('HY000', '[HY000] [Informix][Informix ODBC Driver]Invalid byte in codeset conversion input. (21000) (SQLExecDirectW)')
All the searches I've done imply something to do with LOCALE settings, but I check and they're all set the same:
CLIENT_LOCALE=en_US.819
DB_LOCALE=en_US.819
dbs_collate=en_US.819
If I use the unixODBC 'isql' utility I can connect to and query the data happily.

This is probably due to an multibyte character in the customer table, which can not be converted to Latin 1, ISO 8859-1 from UTF8. Even with same codes set on both CLIENT_LOCALE and DB_LOCALE, an ODBC client makes an internal conversion from UTF-8 to 8859. If there are any 2-byte chars (chars beyond extended-ascii 255) they will not convert to a Latin-1 client. I would look at the data in customer table and identify the problematic data.
It is possible (or likely) that there is an Unicode encoding mismatch.
On my Debian system, the python builds (both 2.7 and 3.4) use UCS-4 encoding. You can verify with this command:
python3 -c "import sys;print(sys.maxunicode<66000 and'UCS2'or'UCS4')"
Once you find the encoding, you need to make sure the Informix odbc.ini file has the same Unicode encoding. In my odbc.ini file,
[ODBC]
;uncomment the below line for UNICODE connection
UNICODE=UCS-4
I hope this resolves your issue.
Thanks for the responses. It was unicode mismatch.
db=pyodbc.connect('DSN=Test1')
db.setdecoding(pyodbc.SQL_WCHAR, encoding='UTF-8')
db.setdecoding(pyodbc.SQL_CHAR, encoding='UTF-8')
db.setencoding(encoding='UTF-8')
By adding setencoding and setdecoding I was able to successfully select data form the Informix DB.

And following the message it turns out that JavaFX was not found. And we had to install the openjfx package. What's the location of the JavaFX runtime JAR file, jfxrt.jar, on Linux?
When I see the package page on the ubuntu package website (http://packages.ubuntu.com/yakkety/openjfx), I realized that it seems compatible with version 8 of the openjdk (openjdk-8-jre).
So I run the jar with this JRE and the blocking point previously encountered seems to have gone but another one has appeared. Apparently the following class seems to be absent (from the classpath) jdk/management/resource/ResourceRequestDeniedException.

So how I can add this library to the classpath please?
Edit 2 :
Just a small clarification regarding the "ResourceRequestDeniedException" exception. I voluntarily call it in my code in the case of a response to an HTTP request with a return code designating an error. For example here is the piece of code concerned by the exception mentioned above.
if( con == null || con.getResponseCode() != 200 )
throw new ResourceRequestDeniedException() ;
Where "con" is an "HttpURLConnection" object.
Edit 3 :
No response including on askubuntu.com. So I create a custom exception (extends Exception) to replace ResourceRequestDeniedException to see if another problem occurs. No additional problems, the application looks to run properly.

# Note that unlike listen_address, you can specify 0.0.0.0, but you must also
# set broadcast_rpc_address to a value other than 0.0.0.0.
I would recommend to set rpc_address: 10.5.0.201 for the 1st node and to retry
I am using the latest Spark master and additionally, I am loading these jars:
- spark-streaming-twitter_2.10-1.1.0-SNAPSHOT.jar
- twitter4j-core-4.0.2.jar
- twitter4j-stream-4.0.2.jar
My simple test program that I execute in the shell looks as follows:
import org.apache.spark.streaming._
import org.apache.spark.streaming.twitter._
import org.apache.spark.streaming.StreamingContext._
System.setProperty("twitter4j.oauth.consumerKey", "jXgXF...")
System.setProperty("twitter4j.oauth.consumerSecret", "mWPvQRl1....")
System.setProperty("twitter4j.oauth.accessToken", "26176....")
System.setProperty("twitter4j.oauth.accessTokenSecret", "J8Fcosm4...")
var ssc = new StreamingContext(sc, Seconds(1))
var tweets = TwitterUtils.createStream(ssc, None)
var statuses = tweets.map(_.getText)
statuses.print()
ssc.start()
However, I won't get any tweets. The main error I see is
14/08/04 10:52:35 ERROR scheduler.ReceiverTracker: Deregistered receiver for stream 0: Error starting receiver 0 - java.lang.NoSuchMethodError: twitter4j.TwitterStream.addListener(Ltwitter4j/StatusListener;)V
at org.apache.spark.streaming.twitter.TwitterReceiver.onStart(TwitterInputDStream.scala:72)
....
And then for each iteration:
INFO scheduler.ReceiverTracker: Stream 0 received 0 blocks
I'm not sure where the problem lies.
How can I verify that my twitter credentials are correctly recognized?
Might there be another jar missing?
NoSuchMethodError should always cause you to ask whether you are running with the same versions of libraries and classes that you compiled with.
If you look at the pom.xml file for the Spark examples module, you'll see that it uses twitter4j 3.0.3. You're bringing incompatible 4.0.2 with you at runtime and that breaks it.
Yes, Sean Owen has given the good reason, after I add two dependency files on the pom.xml file:
<dependency>
<groupId>org.twitter4j</groupId>
<artifactId>twitter4j-core</artifactId>
<version>3.0.6</version>
</dependency>
<dependency>
<groupId>org.twitter4j</groupId>
<artifactId>twitter4j-stream</artifactId>
<version>3.0.6</version>
</dependency>
In this way we change the default twitter4j version from 4.0.x to 3.0.x (http://mvnrepository.com/artifact/org.twitter4j/twitter4j-core), then the incompatible problem will be solved.
