Subject [jira] [Commented] (HIVE-13262) LLAP: Remove log levels from DebugUtils
Date Fri, 11 Mar 2016 08:08:41 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15190622#comment-15190622

Prasanth Jayachandran commented on HIVE-13262:
----------------------------------------------

[~sershe] This patch adds logger with names for different logical pieces in LlapIo. Also removes
some unused methods and classes. I have added parameterized logging all over and guarded some
places with isXXXEnabled where I thought the log line will be expensive. I am not sure if
some lines should go to info/debug/trace level. Can you please comment on RB if you think
some lines should be logged at different level instead?

> DebugUtils has many hardcoded log levels. To enable logging we need to recompile code
with desired value. Instead configure add loggers for these classes with log levels via log4j
properties. Also use parametrized logging in IO elevator.
