Hi,
We are using Cloudera CDH3u5 distribution of HBase (0.90.6). The RS goes
down suddenly & from the logs we see the following exception in the region
server :
2013-08-07 20:36:58,008 INFO org.apache.hadoop.hbase.regionserver.Store:
Completed compaction of 18 file(s), new file=hdfs://
192.168.0.
Lars checked in HBASE-6580 today where HTablePool is Deprecated.
Please take a look.

1stly, why you wanna move away from MongoDB to HBase? well, if it's a RDBMS
we are talking about here, sqoop sounds like the tool you should be using.
But seems it's mongoDB, you will have to look into Flume/Scribe and see if
it's feasible.

Hi Scott,
What do you mean by "Running a major compaction does not significantly
improve the locality."? If there is no other writes on your table
while/after the major compaction, it should be at 100%.
hdfsBlocksLocalityIndex is for the entire node, not just for a specific
table. If you have oth
I'd like to improve block locality on a system where nearly 100% of data
ingest is via bulkloading. Presently, I measure block locality by
monitoring the hdfsBlocksLocalityIndex metric. On a 10 node cluster with
block replication of 3, the block locality index is about 30%, which is
what I'd expe

You are way underpowered. I don't think you are going to get reasonable
performance out of this hardware with so many processes running on it
(specially memory heavy processes like HBase), obviously severity depends on
your use case
I would say you can decrease memory allocation to namenode/dat
Hi Ted,
I am using centOS.
I could not get output of "ps aux | grep pid" as currently the hbase/hadoop
is down in production due to some internal reasons.
Can you please help me in figuring out memory distribution for my single
node cluster ( pseudo-distributed mode) ?
Currently its just 4GB RAM
I found this thread

May be you found this already. Seems like a bug in JVM?

Seems to be the same issue as here:

It says it a jvm bug and it seems right.
You may want to try the very last jvm on your platform (it's unlikely to
work), as well as the jdk 1.6 (it could work
I have just started on a real/near time data loading project working with

Dear HBase Users/Developers,
Please help with issue below:
JVM crashes on HTable initialization. We tested it on JVM 32 bit on SUN and it
works. It works for us on Linux as well. On SUN Solaris 9/10 JVM crashes. Any
ideas?

Table is closed for each Put in writeRow(). This is not efficient.
Take a look at http://hbase.apache.org/book.html#client , 9.3.1 Connections

I don't see hbase.zookeeper.quorum in your config.
Where do you run your zookeeper ?

decrease cache size (say, 1000) and increase batch or just set it as default
if #qualifiers in a row is not too many.
