[jira] [Commented] (DRILL-1343) Drill should timeout after short
time if a storage plugin is unresponsive.
[ https://issues.apache.org/jira/browse/DRILL-1343?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14225841#comment-14225841 ]
Sean Hsuan-Yi Chu commented on DRILL-1343:
------------------------------------------
This issue happened on Impala as well. See https://issues.cloudera.org/browse/IMPALA-1031. Essentially, it takes HBase/Zookeeper a long time to fail if we choose default retry times and timeout.
A solution could be:
In bootstap-storage-plugins for hbase, add these:
"zookeeper.session.timeout": "60000",
"zookeeper.recovery.retry": "0",
"hbase.client.retries.number": 1
According to my test, it works. But I am wondering if this could cause subtle side-effect towards Drill?

> Start drillbit and sqlline with a schema specified, e.g.,
> sqlline -n admin -p admin -u "jdbc:drill:schema=dfs.TpcHMulti;zk=10.10.30.104:5181,10.10.30.105:5181,10.10.30.106:5181"
> Execute one of the following:
> show tables;
> select * from INFORMATION_SCHEMA.`TABLES`;
> The commands hang forever. No exception was thrown in the log file.
> Note that if using zk=local, the second query works with no hanging problems.
