Error when starting spark-shell local on Mac - apache-spark

I get the following error when I try to start spark-shell locally on Mac. Because the error occurs while sc is being created, sc is not available afterwards.
[ender#koders:data] $ spark-shell
Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel).

After searching and investigating the logs, I suspected that it's because my hostname could not be found in /etc/hosts. After changing the hostname from "koders.local" to "koders" which exists inside /etc/hosts, problem solved.

spark-shell throws java.lang.reflect.InvocationTargetException on running

When I execute run-example SparkPi, for example, it works perfectly, but
when I run spark-shell, it throws these exceptions:

As I can see it caused by Illegal character in path at index 42: spark://DESKTOP-JO73CF4.mshome.net:2103/C:\classes, but I don't understand what does it mean exactly and how to deal with that
How can I solve this problem?
I use Spark 3.2.0 Pre-built for Apache Hadoop 3.3 and later (Scala 2.13)
JAVA_HOME, HADOOP_HOME, SPARK_HOME path variables are set.

i face the same problem, i think Spark 3.2 is the problem itself
switched to Spark 3.1.2, it works fine

I've faced the same issue. as of April 2022, I've used spark-3.1.3-bin-hadoop3.2 with winutils.exe (hadoop-3.2.0). It worked

spark giving requirement failed: Literal must have a corresponding value to string, but class String found

I have a spark 2.4.6 with dataframe write as
df
.select((struct(df.columns.map(column): _*)).alias("value"))
.write
.format("kafka")
.options(........)
.save
But after making a jar and doing spark submit in version 3.0.2 it gives:
Exception in thread "main" java.lang.IllegalArgumentException: requirement failed: Literal must have a corresponding value to string, but class String found.

On checking the functions
we have that validation function in 3.0.2
https://github.com/apache/spark/blob/648457905c4ea7d00e3d88048c63f360045f0714/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/literals.scala#L292
but not in the previous version
https://github.com/apache/spark/blob/v2.4.6/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/literals.scala
Is there any resolution to this without upgrading the spark version?
as rebuilding the jar with version 3.0.2 works fine.

exception thrown on worker gets "Task exception could not be deserialized" ClassNotFoundException error

When an exception defined in my application is thrown on a worker, for example in a map:
sc.parallelize(0 until 10000).map(x =>
if (x == 7938)
throw new FatalException("oops")
else
x).sum()
I get a error of the form:
16/04/06 15:07:55 WARN ThrowableSerializationWrapper: Task exception could not be deserialized
java.lang.ClassNotFoundException: $line15.$read$$iwC$$iwC$FatalException
which is propagated to the driver as a SparkException: ReasonUnknown:
org.apache.spark.SparkException: Job aborted due to stage failure: Task 6 in stage 0.0 failed 1 times, most recent failure: Lost task 6.0 in stage 0.0 (TID 6, localhost): UnknownReason
This is a serious problem since I can't diagnose errors in the driver or report them meaningfully to the application user.
If I throw a SparkException, on the other hand, I get a nice:
org.apache.spark.SparkException: Job aborted due to stage failure: Task 6 in stage 1.0 failed 1 times, most recent failure: Lost task 6.0 in stage 1.0 (TID 14, localhost): org.apache.spark.SparkException: oops
I'm guess the class loader deserializing the propagated exception isn't seeing my application jar (or in this case, the class defined in spark-shell), but I haven't been able to find a workaround. Any ideas?
I'm seeing this in an application run through spark-submit, but here's a full example through spark-shell:
$ /usr/local/spark-1.5.2-bin-hadoop2.6/bin/spark-shell

Any ideas?
edit 1:
The relevant code in Spark is in TaskResultGetter.scala:
try {
if (serializedData != null && serializedData.limit() > 0) {
reason = serializer.get().deserialize[TaskEndReason](
serializedData, Utils.getSparkClassLoader)
}
} catch {
case cnd: ClassNotFoundException =>
// Log an error but keep going here -- the task failed, so not catastrophic
// if we can't deserialize the reason.
val loader = Utils.getContextOrSparkClassLoader
logError(
"Could not deserialize TaskEndReason: ClassNotFound with classloader " + loader)
case ex: Exception => {}
}
which calls spark.util.Utils.getSparkClassLoader:
def getSparkClassLoader: ClassLoader = getClass.getClassLoader
which is using the class loader which loaded the Spark jar.

This is a known issue: SPARK-11195. You need to upgrade your Spark to 1.6.0 or 1.6.1.

titan-1.0.0-hadoop1 compatibilty issues with apache-cassandra-3.2

I am trying to connect titan-1.0.0-hadoop1 with apache-cassandra-3.2.
I am using following " titan-cassandra-myfile.properties ":
storage.cassandra-config-dir=titan-1.0.0- hadoop1/conf/cassandra/cassandra.yaml
storage.backend=cassandra
storage.hostname=localhost
When I use gremlin to execute following command:
g=TitanFactory.open("/path to titan/ titan-1.0.0-hadoop1/conf/titan-cassandra-myfile.properties");
I am getting following error:

When I use same configurations with apache-cassandra-1.2.5 and titan-all-0.3.1 , the above config works and it creates a graph.
Please suggest some solution on this , whether is this a compatibility issue or I am doing something wrong.
Thanks,
Laxmikant

Titan 1.0 has been released using Cassandra 2.1.9. I'm almost sure that it's not compatible with Cassandra 3.x because there was a storage engine re-write

Error when writing a repartitioned SchemaRDD to Parquet with Spark SQL

I am trying to write save Spark SQL tables to Parquet files. Because of other issues I need to reduce the number of partitions before writing. My code is
data.coalesce(1000,shuffle=true).saveAsParquetFile("s3n://...")
This throws
java.lang.NullPointerException

The code works fine if I take out the coalesce step and changing the code to use shuffle=true or using repartition throws the same error. I am using spark-1.1.0.
