------------------------------------------------------------------
bq. T3. Client B exhausts retries, marks index disabled with disabletimestamp
of T0. Rebuilder will rebuild as of T0.
But still there is a problem, if client B goes away without making index
disabled, index will stay in ACTIVE state all the time.
How about keeping a count of PENDING_DISABLE? which we will be incrementing
atomically on every PENDING_DISABLE call and decrementing it on ACTIVE call ,
if count=0 make it ACTIVE otherwise keep it PENDING_DISABLE.
And if the client goes away ,use the same threshold for last PENDING_DISABLE
call to make PENDING_DISABLE to DISABLE. WDYT?

> Key: PHOENIX-4785
> URL: https://issues.apache.org/jira/browse/PHOENIX-4785
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.14.0
> Reporter: Romil Choksi
> Assignee: Vincent Poon
> Priority: Blocker
> Fix For: 5.0.0, 4.14.1
>
> Attachments: PHOENIX-4785.v1.master.patch, PHOENIX-4785_test.patch
>
>
> After PHOENIX-4130, we are unable to write to a table if an index is made
> ACTIVE during the retry as client timestamp is not cleared when table state
> is changed from PENDING_DISABLE to ACTIVE even if our policy is not to block
> writes on data table in case of write failure for index.
