-
Summary: HBase Operations Can Fail When Using MAPREDLOCAL
Key: HIVE-21748
URL: https://issues.apache.org/jira/browse/HIVE-21748
Project: Hive
Issue Type: Bug
Components: HBase Handler
Affects Versions: 4.0.0, 3.2.0
Reporter: David Mollitor
https://github.com/apache/hive/blob/5634140b2beacdac20ceec8c73ff36bce5675ef8/hbase-handler/src/java/org/apache/hadoop/hive/hbase/HBaseStorageHandler.java#L258-L262
{code:java|title=HBaseStorageHandler.java}
if (this.configureInputJobProps) {
LOG.info("Configuring input job properties");
...
try {
addHBaseDelegationToken(jobConf);
} catch (IOException | MetaException e) {
throw new IllegalStateException("Error while configuring input job
properties", e);
}
}
else {
LOG.info("Configuring output job properties");
...
}
{code}
What we can see here is that the HBase Delegation Token is only created when
there is an input job (reading from an HBase source). For a particular stage
of a query, if there is no HBASE input, only HBASE output, then the delegation
token is not created and will cause a failure.

You can tell it will fail because an HDFS Token will be created, but it will
not report an HBASE token in the HS2 logs. The following is an example of a
proper setup. If it is missing the HBASE_AUTH_TOKEN it will fail because it
will try to initiate Kerberos handshake and fail.
