Long running compaction on huge hint table.

[varun saluja]

Hi Experts,

We are facing issue on production cluster. Compaction on system.hint table
is running from last 2 days.


pending tasks: 1
   compaction type   keyspace   table     completed          total
            unit   progress
              Compaction     system   hints   20623021829   *877874092407*
 bytes      2.35%
Active compaction remaining time :   0h27m15s


Active compaction remaining time shows in minutes.  But, this is job is
running like indefinitely.

We have 3 node cluster V 2.1.7. And we ran  write intensive job last week
on particular table.
Compaction on this table finished but hint table size is growing
continuously.

Can someone Please help me.


Thanks & Regards,
