Is there any command that I can learn the size of a table at Hbase? I use Hbase to hold my crawl data from Nutch.
If you are running hbase on hadoop the following command can be used
hadoop fs -du [path]
[path]
has to be replaced with the value of hbase.rootdir
in hbase-site.xml
the output will look like:
$ hadoop fs -du /hbase
4056 hdfs://127.0.0.1:9000/hbase/-ROOT-
22307 hdfs://127.0.0.1:9000/hbase/.META.
0 hdfs://127.0.0.1:9000/hbase/.corrupt
0 hdfs://127.0.0.1:9000/hbase/.logs
0 hdfs://127.0.0.1:9000/hbase/.oldlogs
1716 hdfs://127.0.0.1:9000/hbase/Table1
1472 hdfs://127.0.0.1:9000/hbase/Table2
1498 hdfs://127.0.0.1:9000/hbase/Table3
1320 hdfs://127.0.0.1:9000/hbase/SampleTable
The size displayed here is in bytes.
If you are running hbase on local filesystem (OS filesystem) then you can use normal du
command.
This will give you a rough idea about size of the table in Hbase.
To count rows/columns in a table you need to run a map/reduce program. HBase ships with a m/r that does that see here
