Yusaku Sako commented on AMBARI-8022:
-------------------------------------

[~tedyu@apache.org] / [~devaraj]
There's v1 and v2 posted.  Which one do we want?
v1 says to remove "hbase.hstore.flush.retries.number", while v2 does not have this entry.
>From the description, we do want to remove it, correct?
Also, if we want 4GB as the default heapsize, shouldn't the value be 4096?  Is 4196 intentional?

> 1. retries.number should not be set (use the default instead)
> 2. Major compaction should be set to the 604... number rather than the 864... number
Ambari is using now.
> 3. block multiplier should be 4 not 2.
> In addition, hbase-env.sh uses a very small heap size for regionservers. This needs to
be increased to 4GB.
