try. We allow such a retry will cause not getting back all the
results. This is a serious problem and this Exception way
helps there. You can try increasing the scan time out period at client
side. This should help.

Hi All,
Is there a way to let scanner finish scanning all regions without throwing this
kind of error? I'm using scan with filter MUST_PASS_ALL, and I observe that
whenever the result data is smaller (let's say 10%) compare to another filter
with larger result (let's say 80%), it always failed.
mparator problem: Why pattern "u" has the same result
as ".*u.*" ?
"u" is part of "hung", producing a match.
Do you want to find string whose value is "u" (not a substring) ?
In that case you can specify "^u$"
Cheers
On S
n execute it, the result is "hung".
Question is why the SingleColumnValueFilter do not abide the regex comparator?
Or why is regex comparator "u" is the same as ".*u.*"?

@Bryan,

distributed writes.
Are your regionservers starved for CPU? Either way, I'd try the java7 G1 GC on
one regionserver and report back. We run with 25GB heaps and never have long
pauses, so 16GB should be fine with enough CPU.

Dear All,
My current hbase environment is heavy write cluster with constant 2000+ insert
rows / second spread to 10 region servers.
Each day I also need to do data deletion, and that will add a lot of IO to the
cluster.
The problem is sometimes after a week, one of the region server will crash
Hi HBase Users,
I'm using hbase 0.96 and currently testing hbase master high-availability.

Then when I kill -9 the 1st master (active), it always(?) took 2 minutes for
the 2nd mast

Thanks for the additional information.
Looks like HA namenode with QJM is not covered by current code.
Mind filing a JIRA with summary of this thread ?

We ask for Closeable interface.
Did the error persist after you replaced with the hadoop-hdfs-2.2.0.jar ?

Hi All,
When stopping master or regionserver, I found some ERROR and WARN in the log
files, are these errors can cause problem in hbase:
13/11/21 09:31:16 INFO zookeeper.ClientCnxn: EventThread shut down

@xieliang: I will try the PrintGCApplicationStoppedTime, thank you.
About loading, total requestPerSeconds is around 15000~3 for 9 servers,
with numberOfOnlineRegions = 136.
I also just uploaded the log files of gc and regionserver into dropbox:
