Dear all,
I have an internal cluster of 11 machines with Hadoop and Hbase installed on it.
I created a table with 3 column families and was trying to do batch inserts of
75000 rows from a SQL database using Java.
I get the following error:
Exception in thread "main"
org.apache.hadoop.hbase.client.RetriesExhaustedWithDetailsException: Failed
74999 actions: NotServingRegionException: 74999 times, servers with issues:

org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation.processBatch(HConnectionManager.java:1485)

org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation.processBatchOfPuts(HConnectionManager.java:1499)
at org.apache.hadoop.hbase.client.HTable.flushCommits(HTable.java:859)
at
com.musigma.hbaseTrigger.HBaseImport.batchInserts(HBaseImport.java:137)
at com.musigma.hbaseTrigger.HbaseTrigger.main(HbaseTrigger.java:64)
The machine on which the error occurs has a lot of free space(67 %) and Hbase
is running successfully on it.
When I reduce the batch inserts from 75000 to 50000, my code works and the data
is inserted successfully.
I am not understanding what exactly is happening in Hbase which is causing this
error to occur.
Thanks and Regards
Prakrati
