I wonder if that the 'backspace' key can't take effect during create a table

[QI Congyun]

Hello expert,

The HBASE is configured, there are 3 node b in my test environment, the 1st 
node is master, the 2nd and 3th is region-servers.

When the Hbase is launched via the command 'start-hbase.sh', I try to create a 
new table by HBase shell.

I can create some tables via HBASE shell. But I don't understand why the 
character can't be deleted by click the 'backspace' key of the key-board if 
some wrong character is input via the key-board? I wonder if the incorrect 
character can' be deleted at the HBASE shell or some incorrect configuration is 
done?

Thanks.

jus will show the processid.No need to go for ps-ef.
currently below process ids are running in my terminal

Does HBase REST API support bulk delete?

[Duo]

Hi experts,

I noticed that RemoteHTable supports bulk delete

delete(List deletes)
Deletes the specified cells/rows in bulk.


However from some online documentations, for example,

https://archive.cloudera.com/cdh5/cdh/5/hbase/apidocs/org/apache/hadoop/hbase/rest/package-summary.html

I cannot find REST APIs to do bulk delete. I can find REST APIs to do bulk
insert by specifying a false row key in the REST url.

Is bulk delete supported in REST APIs in HBase?

Thanks,
Duo

Re: stop-hbase.sh is not stopping regionservers

[Ted Yu]

jps may not show the process.

Have you tried using 'ps' command to check 13827 ?

Which hbase release are you using ?

Did you make any non-default config change ?

Cheers

Hi,

Its internal...and from jps track the process running for regionserver.
and stop it with kill -9 pid

$ start-hbase.sh
localhost: starting zookeeper, logging to
/Users/Aditya/Big_Data/hbase-1.0.3/logs/hbase-Aditya-zookeeper-Manojs-MacBook-Air.local.out
starting master, logging to
/Users/Aditya/Big_Data/hbase-1.0.3/logs/hbase-Aditya-master-Manojs-MacBook-Air.local.out
regionserver running as process 13827. Stop it first.

$kill -9 13827
$jps ---it will not show region server

Re: HBase 1.0 Per Put TTL Not Being Obeyed On Replication

[Anoop John]

At server side (RS) as well as at client side, put the config
"hbase.client.rpc.codec" with a value
org.apache.hadoop.hbase.codec.KeyValueCodecWithTags. Then u will
be able to retrieve the tags back to client side and check
