Mujtaba Chohan commented on PHOENIX-177:
----------------------------------------
[~jesse_yates] Does this mean I would *always* need
_phoenix-hadoop<version>-compat-x.x.x.jar_ and
_phoenix-hadoop-compat-x.x.x.jar_ on HBase region servers classpath from now
on? Otherwise it gets in following exception on upserting index while using
HBase 0.98.4 on Hadoop1/2:
org.apache.phoenix.execute.CommitException:
org.apache.hadoop.hbase.client.RetriesExhaustedWithDetailsException: Failed
24000 actions:
org.apache.phoenix.hbase.index.builder.IndexBuildingFailureException: Failed to

> Project: Phoenix
> Issue Type: Sub-task
> Affects Versions: 5.0.0, 4.1
> Reporter: ryang-sfdc
> Assignee: Jesse Yates
> Labels: enhancement
> Fix For: 5.0.0, 4.1
>
> Attachments: phoenix-177-4.0.patch, phoenix-177-master-v0.patch,
> phoenix-177-master.patch

> I'd like to know how much cpu, physical io, logical io, wait time, blocking
> time, transmission time was spent for each thread of execution across the
> hbase cluster, within coprocessors, and within the client's phoenix
> threadpools for each query.
> Here are some of the problems I want to solve:
> 1) every component has one or more configurable threadpools, and I have no
> idea how to gather data to make any decisions.
> 2) queries that I think should be fast turn out to be dog slow, e.g., select
> foo from bar where foo like 'abc%' group by foo Without attaching a profiler
> to hbase, which most people won't bother with, it's not clear why it's slow.
