Hi!
I'm trying to set up a test environment locally on my laptop and it
works if I use the standard embedded derby driver. As soon as I add a
hive-site.xml, I tried both MySQL and Derby with servers definitely
running and the respective parameters set in that hive-site.xml, I get
the following exception:
FAILED: Error in metadata: javax.jdo.JDOFatalDataStoreException:
Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago.
The driver has not received any packets from the server.
NestedThrowables:
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications
link failure
The last packet sent successfully to the server was 0 milliseconds ago.
The driver has not received any packets from the server.
FAILED: Execution Error, return code 1 from
org.apache.hadoop.hive.ql.exec.DDLTask
If I switch back to the embedded driver by erasing hive-site and
restarting hadoop, it works again.
Does anyone have any idea why that error occurs?
Thanks,
Anja
