We now have a problem about hbase export.
We follow these process to export hbase table:
(1)We change the hdfs permissions to drwxrwxr-x by executing command "sudo -u hdfs hdfs dfs -chmod 775 /".
(2)excute the command:"hbase org.apache.hadoop.hbase.mapreduce.Export 'test' file:///tmp/hbase123/" to export hbase table to /tmp
(3)back up the file on /tmp
The problem is the log message show the mission is successed:
"17/04/18 11:58:51 INFO mapreduce.Job: Job job_1484613653857_0370 completed successfully"
But the file "hbase123" on /tmp is empty!!
Is there any read/write permissions issue?
