Hi,
When I export large table with 460+ regions, I saw the exportSnapshot job
fail sometime (not all the time). The error of the map task is below: But I
verified the file highlighted below, it does exist. Smaller table seems
always pass. Any idea? Is it because it is too big and get session timeout?
org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hdfs.server.namenode.LeaseExpiredException):
No lease on
/hbase/.archive/rich_pin_data_v1/7713d5331180cb610834ba1c4ebbb9b3/d/eef3642f49244547bb6606d4d0f15f1f
File does not exist. Holder DFSClient_NONMAPREDUCE_279781617_1 does
not have any open files.
