Sushanth Sowmyan commented on HIVE-16973: ----------------------------------------- HIVE-17083 is in now. And looking at the previous test run, your patch upload seems to have happened when the ptest system was having some issues. I'm re-uploading the master patch so that it picks that up and runs. > Fetching of Delegation tokens (Kerberos) for AccumuloStorageHandler fails in > HS2 > -------------------------------------------------------------------------------- > > Key: HIVE-16973 > URL: https://issues.apache.org/jira/browse/HIVE-16973 > Project: Hive > Issue Type: Bug > Components: Accumulo Storage Handler > Reporter: Josh Elser > Assignee: Josh Elser > Attachments: HIVE-16973.001.patch, HIVE-16973.002.branch-2.patch, > HIVE-16973.003.branch-2.patch, HIVE-16973.004-branch-2.patch, > HIVE-16973.004.branch-2.patch, HIVE-16973.004-master.patch > > > Had a report from a user that Kerberos+AccumuloStorageHandler+HS2 was broken. > Looking into it, it seems like the bit-rot got pretty bad. You'll see > something like the following: > {noformat} > Caused by: java.io.IOException: Failed to unwrap AuthenticationToken > at > org.apache.hadoop.hive.accumulo.HiveAccumuloHelper.unwrapAuthenticationToken(HiveAccumuloHelper.java:312) > > at > org.apache.hadoop.hive.accumulo.mr.HiveAccumuloTableInputFormat.getSplits(HiveAccumuloTableInputFormat.java:122) > > {noformat} > It appears that some of the code-paths changed since when I first did my > testing (or I just did poor testing) and the delegation token was never being > fetched/serialized. There also are some issues with fetching the delegation > token from Accumulo properly which were addressed in ACCUMULO-4665 > I believe it would also be best to just update the dependency to use Accumulo > 1.7 (drop 1.6 support) as it's lacking in this regard. These changes would > otherwise get much more complicated with reflection -- Accumulo has moved on > past 1.6, so let's do the same in Hive. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
