Just to add, I verified that hbase-client-2.0.0-SNAPSHOT.jar (which
contains org.apache.hadoop.hbase.HColumnDescriptor) is in hbase class path.

Hi Soufiani,
Can you try changing your configuration to have region server listen on
0.0.0.0:16020 and master listen on 0.0.0.0:16000 ?
127.0.0.1 being local loopback will not be accessible from outside.

replicated successfully in cluster B.
I went through the WALEdit API and it is not obvious to me if it is
possible to retrieve the attributes set on the row mutation.
Kindly let me know your suggestions.
Regards,
Sreeram
Thank you very much Ted. I understand fetching the tags will fetch the
associated attributes for a mutation. Will try out the same.

In CellUtil, there is the following method:

to check if there are any limits on the number of rows per
cluster.
Will it be advisable to split the cluster in such situation into two or
more independent clusters? Will there be any impact to the read/write
throughput/latency as the table grows over time?
Please advise.

Hi Ted,
>From the link
"Around 50-100 regions is a good number for a table with 1 or 2 column
families. Remember that a region is a contiguous segment of a column
family.".
This number 50-100 regions per table at the level of individual region
server or for the entire cluster ?
Th
WAL files in HDFS need to be written to ? The network
drive has synchronous replication across data centers. If the WAL files can
be written to the replicated network drives, can we recover in-flight data
in the passive cluster and resume operations from there ?

the actual size of row in HBase.
Is my understanding correct? Kindly let me know.

Test.TestWALEditCP was loaded successfully with priority (536870912).
Any thoughts what can be going wrong ?

PS: I use HBase version 1.2.0
only the latest values for
the column, provided they match the filter.
Is this the expected behaviour of ValueFilter? Any suggestions if I
must be setting any options to skip the older values from coming in
the result?
Thank you

that I use is HBase 1.2.0-cdh5.8.2
Kindly let me know

Thanks,

( or may be its not obvious for me).
The version of HBase that I use is 1.2.0-cdh5.8.2
Any help on this regard ?
Thanks,

to influence HBase to use higher values for the
socket read/write buffers when it does replication.
Any thoughts from the community on the same?

info:regioninfo is actually a serialized Java object (HRegionInfo). What you

Thanks Doug. I am looking more from HBase shell for this.

Hi,
I am looking for options to batch the output of HBase scan with prefix filter,
so that it can be paginated at the front end.
Please let me know if there recommended methods to do the same.
Thank you.
