Can you trace master log to see why there were two region servers on that ip
with different start codes ?
Thanks

we checked the regionserver using ps aux,we find only one regionserver
instance.
we checked zookeeper,using ls,we find there is only one regionserver info.

Yes testing custom filters in HBase are sort of pain.

by my understanding, even if we started two region server on one machine,
the master will check if the region server with the same ip and port had
registered, if registered ,the later one will be ignored. you can see the
source code in org.apache.hadoop.hbase.master.ServerManager

Somehow I missed the scan result in your first email. So, can you pass
a LongColumnInterpreter instance instead of null?

You may need to setup your Eclipse workspace and search using
references etc.To get started, this is one class that uses TimeRange
based matching ...
org.apache.hadoop.hbase.regionserver.ScanQueryMatcher
Also - Get is internally implemented as a Scan over a single row.
Hope this gets you started.
Thanks, it's really better !
I've read that by default it supports only Long values, that's why I was using
a null ColumnInterpreter.

Hi Jay,
Yes, the whole log would be interesting, plus the logs of the datanode
on the same box as the dead RS.
What's your hbase & hdfs versions?
The RS should be immune to hdfs errors. There are known issues (see
HDFS-3701), but it seems you have something different...
This:
> java.nio.channels.
We should fix the reference then. Where did you read it?

Thanks for the quick reply Nicolas. We are using HBase 0.94 on Hadoop
1.0.3.
I have uploaded the logs here:

Appreciate your help in figuring this out.
Thanks,

Glad to hear that answers & suggestions helped you!
The format you are seeing is the output of
org.apache.hadoop.hbase.util.Bytes.toStringBinary(..) method [1]. As you
can see below, for "printable characters" it outputs the character itself,
while for "non-printable" characters it outputs data in

Hi Jay,
As you said aldready, the pipeline for blk_5116092240243398556_489796
contains only dead nodes, and this is likely the cause for the wrong
behavior.
This block is used by a hlog file, created just before the error. I
don't get why there are 3 nodes in the pipeline, I would expect only
2. D
unfortunately I can't remember/find it :( and I see in AggregationClient's
javadoc that :
"Column family can't be null" , so I suppose I should have read it at first !
Thanks again

Hey guys,
in my application the HBase timestamp is used as version in my logic.
I would like to know what is the best way to insert a new record and get its
timestamp.
I have come up with two possibilities:

I like having access to the web admin pages that HBase, HDFS, etc
provide. I can't find a way to put them behind SSL, though. For the
HMaster it's easy enough (nginx+SSL as a reverse proxy), but the
HMaster generates links like data01.company.com:60030. Is there a way
to change the scheme and port
Hi,
Are you talking about as coprocessor or MapReduce input? If it is the first
then it is up to you (the client). If it is the latter I am not sure that
-if scans were changed to be parallel (assuming they are sequential now)-
the whole job would be noticeably faster. But I am interested in an an
