I got the dump of the problematic rs from web ui:
http://pastebin.com/4hfhkDUw
output of top -H -p PID: http://pastebin.com/LtzkScYY
I also got the output of jstack but I believe it's already in the dump
so I do not paste it again. This time the hang lasted about 20 minutes.
于 2014/7/9 12:48,
I noticed the blockSeek() call in HFileReaderV2.
Did you take only one dump during the 20 minute hang ?
Cheers

Hey,

Make sure you are placing 2.4 version hadoop jars in hbase/lib folder so
that HBase picks correct jars during runtime. This needs to be done across
all the nodes in the cluster.

In you mvn command I noticed that assembly:single was missing.
Is this a typo ?
Btw there is no hadoop-core jar for Hadoop 2.4.0

Hi Team,
Could you please help me to resolve below issue.
In my hbase table, i've a 30 records. I need to retrieve records based on

HI Rajesh,
If you know the rowkeys already, you don't need to perform a scan, you can just
perform a get on the list of rowkeys
e.g.
ListGet RowKeyList = new ArrayListGet();
# for each rowkey
RowKeyList.add(new Get(Bytes.toBytes(rowkey)));
Result[] results = table.get(RowKeyList);
for
Hi Ian,
Thank you very much of the solution. Could you please explain at what are
the use cases we need to use RowFilter?

Hi Rajesh
From personal use, the rowFilter allows for finer grained results when
performing a large scan where the row keys don't exaclty match your criteria.
For example if you use start and end rows to constrain your scan, the results
may contain some results that you don't want and you can

Hi Rajesh,
It looks like the filter list combines filters with 'AND' operator.
In your case you had two 'equal' rowfilters and expected each return a result.

Hi,
Does new hbase version(0.99) supports incremental backup using snapshots?
If not supported in current releases, is it planned to add in future
releases?
can we export snapshots to local file system directly?
Thanks
