Subject [jira] [Updated] (HIVE-13643) Various enhancements / fixes to llap cli tools
Date Fri, 29 Apr 2016 07:36:12 GMT


Siddharth Seth updated HIVE-13643:
    Attachment: HIVE-13643.02.patch

Updated patch.
- Capitalized LLAP in log lines.
- This only work with slider apps. Min length of service hosts from config has to be 2. Moved
the checks a bit to make this simpler, and improved logging.

This patch contains 2 more changes.
1. adds a configurable appTimeout to llap status - when waiting for the yarn app to show up
2. Changes llap service driver to pick up the name correctly from the config if it is not
passed in on the command line. (The earlier behaviour would result in the app launching wiht
a name llap0 (default) - and daemons registering with the name in hive-site)

[~prasanth_j] - another change I'd like to make is to set the log level via hiveconf. Do you
know what is required for this ? Once the process starts up - it'll pick up the log level
from the config file. Assuming something specific needs to be done to make this work.
I can make that change here, or a separate jira depending on when jenkins ends up running
for this.
