Subject [jira] [Commented] (HIVE-14213) Add timeouts for various components in llap status check
Date Tue, 12 Jul 2016 23:16:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15373913#comment-15373913

Siddharth Seth commented on HIVE-14213:
---------------------------------------

bq. Why do we need a separate set of config settings? 
That's really only for the case where defaults are incorrect. A bunch of these settings are
common to multiple commands. e.g. the yarn logs command, or yarn application -list would use
the parameters for retry. Similarly various dfs commands. I don't think the main config settings
can be changed in yarn-site/core-site just for this command - hence the new config variables.

bq. On the same note, if the component settings are already set, and the new ones are not
set, this will override them with defaults. Perhaps we can just have the default constants
for the original parameters (from YARN etc.), and set them if not already set? If the user
wants to change them they can just set the originals too
Didn't quite understand this. If the new configs are set - they'll be used. Otherwise the
defaults will be used. The defaults are supposed to be good enough.

> The llapstatus check connects to various compoennts - YARN, HDFS via Slider, ZooKeeper.
If either of these components are down - the command can take a long time to exit.
