Subject [jira] [Comment Edited] (HIVE-14213) Add timeouts for various components in llap status check
Date Tue, 12 Jul 2016 06:17:11 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15372231#comment-15372231

----------------------------------------------------------------

The patch adds various timeouts.

Hadoop and timeouts seems to be quite broken at the moment. Have added some configurable properties
in the patch - within LlapStatus itself to work around some of these problems if required.
Ideally, these are only temporary, and should not be added to HiveConf.

The defaults provide between 10-15seconds to communicate with a service (using hadoop 2.7.x)

The patch also changes the cli-log4j file to send all output to a log file by default.

cc [~prasanth_j], [~sershe] for review.

If either of these components are down - the command can take a long time to exit.
