Hi all, I wrote a MR job for inserting rows into hbase. I open a CSV file which is present in the hdfs and i use put function in the map() to insert into hbase.
This technique worked just for 50% and the job got killed.. the log file is here : http://pastebin.com/12gmF3Z6 Why is this happening ? and The console was like this : 10/12/07 17:52:48 INFO mapred.JobClient: map 49% reduce 0% 10/12/07 17:54:31 INFO mapred.JobClient: map 50% reduce 0% 10/12/07 17:58:01 INFO mapred.JobClient: map 51% reduce 0% 10/12/07 18:06:41 INFO mapred.JobClient: map 52% reduce 0% 10/12/07 18:09:24 INFO mapred.JobClient: map 51% reduce 0% 10/12/07 18:09:26 INFO mapred.JobClient: Task Id : attempt_201012071646_0001_m_000025_0, Status : FAILED Task attempt_201012071646_0001_m_000025_0 failed to report status for 600 seconds.
