Sahil Takiar commented on HIVE-18652:
-------------------------------------
A few other changes came in as part of this patch:
* Exposed a couple more metrics from Spark; I missed these when working on
HIVE-18651
** Specifically, {{InputMetrics#recordsRead}},
{{ShuffleReadMetrics#localBytesRead}}, {{#remoteBytesReadToDisk}},
{{#recordsRead}}, and {{ShuffleWriteMetrics#shuffleRecordsWritten}}
* Changed the order that metrics are printed, tried my best to find an order
from most-relevant to least-relevant (this required changing the order in
{{SparkMetricsUtils#collectMetrics}}
> Print Spark metrics on console
