Duo Zhang updated HBASE-14969:
------------------------------
Attachment: HBASE-14969-addendum-branch-1.patch
Patch for branch-1.
On master, we have this
{code:title=BaseLoadBalancer.java}
// Regions of these tables are put on the master by default.
private static final String[] DEFAULT_TABLES_ON_MASTER =
new String[] {AccessControlLists.ACL_TABLE_NAME.getNameAsString(),
TableName.NAMESPACE_TABLE_NAME.getNameAsString(),
TableName.META_TABLE_NAME.getNameAsString()};
{code}
So on master we do not have the problem. But I suggest we should also apply the
patch for master.
[~liyu] Is this patch OK for you?
Thanks.

> In HBASE-8329 we added a throughput controller for compaction, to avoid spike
> caused by huge IO pressure like network/disk overflow. However, even with
> this control on, we are still observing disk utils near 100%, and by analysis
> we think this is caused by flush, especially when we increase the setting of
> {{hbase.hstore.flusher.count}}
> In this JIRA, we propose to add throughput control feature for flush, as a
> supplement of HBASE-8329 to better control IO pressure.
