org.apache.hadoop.hive.metastore.HiveMetaException: Failed to load driver
*** schemaTool failed ***
{code}
When I tried a dryrun,
{code}
sudo -u hive /usr/hdp/2.3.0.0-2545/hive/bin/schematool -dryRun -dbType mysql
-upgradeSchema
{code}
it doesn't seem to fail on the driver load issue, though it was failing on
something else.
I am assuming this is related to us missing some libraries during
rolling-upgrades.
But we need to find out what exactly it is that is missing. Is it
mysql-connector-java.jar ? Does it need to be readable by hive user, given the
ugpradeSchema command above is running as hive?
