hi, i failed to connect a remote hbase server with java api , i added the
conf from hbase and hadoop to HbaseConfiguration.
hbase shell can work no problem in remote server.
when i use java api to connect the remote hbase,get this error
at first i think if the centos system closes some ports should be open?
and i open the 2181 and 2888 ,3888,60010,60030 ,and hadoop server port ,but
it still get this error
or something else i didnt notice. thanks for any help.
