Profiling Hive / Metrics
Hey devs,
My Hive reducers are running for too long. I wan't to profile Hive and
collect metrics so as to find where most of the time is spent in execution.
Can any one tell me where to start ? Are any profilers attached to Hive by
default?
Any help is appreciated.
Thanks,
jS

Hello,
Unfortunately there are no Hive metrics.
Hadoop has metrics, but not sure they would help you, as they are on a much
lower level.
