emr cluster node down - unable to access hive tables
I am running my spark job on Emr cluster and I have been using Hive Tables as my data source which uses hdfs:///home/hadoop/database directory as target-dir for my database directory.
When I ran my spark job, it lost a cluster node and it came back up after sometime.
Now I am trying to run my read my Hive Tables and it throws Could not obtain block.
Is it because the particular table is stored in the node (The node that sometimes down) ?
When a EMR cluster node is down, will it restart and have none of the previous HDFS data stored?
