Lefty Leverenz commented on HIVE-13494:
---------------------------------------
Doc note: This removes *hive.llap.queue.metrics.percentiles.intervals* and
adds *hive.llap.io.decoding.metrics.percentiles.intervals* so the changes need
to be documented in the LLAP section of Configuration Properties for release
2.1.0.
* [Configuration Properties -- LLAP |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-LLAP]
Question: Why is *hive.llap.queue.metrics.percentiles.intervals* included at
the end of the description for
*hive.llap.io.decoding.metrics.percentiles.intervals* (or are "\n" and "+" on
the previous line errors)?
