I am facing the following error when running sstabledowngrade :
Error rewriting

When I checked the system log, the stacktrace suggests something wrong with ldap config but I don't understand what.

Attempting to use directives for an Apache module that is not enabled will result in apachectl configtest messages like the following:Example Error Output
(13)Permission denied: AH00957: HTTP: attempt to connect to 127.0.0.1:9090 (127.0.0.1) failed
The Apache error log may have more information.
I tried verifying logs and searched the error in online but unable to find anything. Can someone please help with the same.
I am at my wits end!
I have a minimal install of Ubuntu Server 18.04 and OpenJDK 11 (headless).
Downloaded, to a local folder are the java 9+ binaries for Derby (db-derby-10.15.2.0-bin)
Path and Environment settings are all correct!
When I start the server startNetworkServer -h 0.0.0.0, I get an error when doing a simple connect using the ij command line tool
ij> connect 'jdbc:derby://localhost:1527/dbname;create=true';
ERROR XJ041: DERBY SQL error: ERRORCODE: 40000, SQLSTATE: XJ041, SQLERRMC: Failed to create database 'dbname', see the next exception for details.::SQLSTATE: XBM01::SQLSTATE: XJ001
The derby.log file makes reference to:
java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "getenv.SOURCE_DATE_EPOCH")
Looking further into this error, I learned that I somehow need a security.profile. I found this website that seemed to be the answers to my problems. https://www.javacodegeeks.com/2020/04/apache-derby-database-jvm-security-policy.html
Following these pretty straight-forward instructions, I get:
java.security.AccessControlException: access denied
org.apache.derby.shared.common.security.SystemPermission( "engine", "usederbyinternals" )
For the next person who has this strange problem (it seems to happen with some regularity, here's a simple workaround, copied from this FAQ page at Chalmers Institute of Technology:
Q: When we try to create a database in Derby and the database explorer in NetBeans, we get one or more of the following error(s):
An error occurred while creating the database:
java.sql.NonTransientConnectionException: DERBY SQL error: ERRORCODE:
40000, SQLSTATE: XJ041, SQLERRMC: ...
Caused by: java.security.AccessControlException: access denied
("java.lang.RuntimePermission" "getenv.SOURCE_DATE_EPOCH")
A: This is some kind of missconfiguration in the JVM with a very aggressive security policy that doesn't allow applications to fetch the time on the system (since epoch). The solution is to edit ~/.java.policy or [java.home]/lib/security/java.policy and add the following:
grant {
permission java.lang.RuntimePermission "getenv.SOURCE_DATE_EPOCH", "read";
};
If you are on Windows you can read about where this policy file is supposed to be located here;
https://docs.oracle.com/javase/7/docs/technotes/guides/security/PolicyFiles.html
Apache-Derby is a database management system prepared for a multi-user environment, therefore, when you execute the startNetworkServer -h 0.0.0.0 instruction, you are telling it by default to take certain security into account, and that is why it does not let you do an insecure connection such as ij> connect 'jdbc:derby://172.16.17.31:1527/BBDD_server;create=true';
because you are connecting without specifying username and password, so you should either connect by specifying username + password, or start the server without any security:
startNetworkServer -h 0.0.0.0 -noSecurityManager

i got this error when i am trying to connect peers running in different machines .I found this error in docker logs of orderer.There is an error in docker logs of peer2 running in different machine
Failed obtaining connection: Could not connect to any of the endpoints: [orderer.example.com:7050]
You can find the orderer.yaml file at fabric-samples/config folder.
Going through the fields and their respective comments in orderer.yaml and core.yaml can help you to understand the method of configuring the network(orderer/peer).
And here you can get the info related to TLS.
I am fairly new to Linux (and brand new to chef) and I have ran into an issue when setting up my chef server. I am trying to create an admin user with the command
sudo chef-server-ctl user-create admin Admin Ladmin admin#example.com
examplepass -f admin.pem
but after I keep getting this error:
ERROR: Connection refused connecting...
ERROR: Connection refused connecting to https://127.0.0.1/users/, retry 5/5
ERROR: Network Error: Connection refused - Connection refused
connecting to https://..., giving up
Check your knife configuration and network settings
I also noticed that when I ran chef-server-ctl I got this output:
[2016-12-21T13:24:59-05:00] ERROR: Running exception handlers Running

I read that this error is due to a prerequisite mistake but I'm uncertain as to what it means or how to fix it. So any input would be greatly appreciated.
Your server does not have a valid FQDN (aka full host name). You'll have to fix this before installing Chef server.

I have seen this reported in a number of places but no solution. Is this error because we are behind a corporate firewall, or is this due to something else? Please advise.
I had proxy set as environment variables, but it appears they are not being picked up. Adding them in sbt directly worked for me.
Edit $SPARK_HOME/sbt/sbt
For example,
EXTRA_ARGS="-Dhttp.proxySet=true -Dhttp.proxyHost=myproxy.mycompany.com -Dhttp.proxyPort=80 -Dhttps.proxySet=true -Dhttps.proxyHost=myproxy.mycompany.com -Dhttps.proxyPort=80 -Dftp.proxySet=true -Dftp.proxyHost=myproxy.mycompany.com -Dftp.proxyPort=80 -Dhttp.nonProxyHosts=mydomain -Dhttps.nonProxyHosts=mydomain -Dftp.nonProxyHosts=mydomain"
