how to split region in hbase shell?
I found one of 4 region server is heavy load than other. and I want to
split region manully.
from the web ui
name: vc2.url_db,,1398174763371.35a8599a5eb457b9e0210f86d8b6d19f.
region serverapp-hbase-1:60030
start key
end key \x1F\xFE\x9B\xFA\x95\x91\xB7\xF0\x9FX\x83\xC9\xBFw\xBD\xDE
request 107360630
I want to split this region. I tried
hbase(main):004:0> split 'vc2.url_db'
,'\x1F\xFE\x9B\xFA\x95\x91\xB7\xF0\x9FX\x83\xC9\xBFw\xBD\xDE'

Have you checked master log to see if the request was received ?
What hbase version are you using ?
>From the command, looks like you were specifying end key. Can you try
