Hi Nick,
This is output of the command "java -version"
$ java -version
java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)
We have been using G1GC for quite a long time.

I don't think there's many folks using G1 in production for HBase yet. Out
of curiosity, what JVM and version are you using? I heard G1 got much
better somewhere after 1.7u60, though I don't have personal experience with
it.

Yeah, I've read bunches of articles on java GC, including the famous one
you mentioned. We don't pass any specific GC params to JVM, except the
"-XX:+UseG1GC" flag.

Yeah, I know a heap dump would work, but I'm a little worried about dumping
22GB of data on a production server, since it could take quite a while, and
make the recovery more slower.

I just pushed a feature branch for an AsciiDoc POC, called HBASE-11533. See
the JIRA too. Please check it out.
You can do mvn clean pre-site, and look at the docs in target/docs. You
will get a failure but that's nothing to do with this. If you run the
following, you should get no failure, and you

Hi Ted，
KeyOnlyFilter may improve the scan speed but I don't think the scan may
finish less than leaseTimeout in such case；
>From the HRegionServer#get I see：
HRegion region = getRegion(regionName); here getRegion may throw

For isSuccessfulScan(), I see:
scan.setBatch(1)
scan.setCaching(1)
scan.setFilter(FirstKeyOnlyFilter.new())
How about adding a KeyOnlyFilter as well ?

Finally I resolved the issue, the RC is :region_mover will call
isSuccessfulScan to scan the startkey of the moved region which filled with
lots of expired cells，so it seems scan hang；
I think isSuccessfulScan is just to test whether the moved region is

I've followed advices, ZK connections on server side are stable.

Hi,
The first thing I'd want to know is which memory poor is getting filled.
There are several in the JVM.

Thanks Stack,
Will check the logs for reason. I'm only disabling compaction during
dynamic splits (~10 mins), so it's acceptable in my case.

Usually, a compactions says what provoked it in the log and why it a major

Ah! I need run
admin.modifyTable(tableNameBytes, tableDescriptor)
Will try it soon...

This is what setCompactionEnabled() does:
public HTableDescriptor setCompactionEnabled(final boolean isEnable) {
setValue(COMPACTION_ENABLED_KEY, isEnable ? TRUE : FALSE);
return this;

yes, one of them (random) gets more connections than others.
9.3.1.1 Is OK.
I have 1 HConnection for logical module per application and each
ServletRequest gets it's own HTable. HTable closed each tme after
ServletRequest is done. HConnection is never closed.

Phoenix 2.x - HBase 0.94.x

However, if you google around you'll find that some people have gotten
