Hello !

 

Shutdown / close of WAL failed: org.apache.hadoop.hdfs.server.namenode.LeaseExpiredException: No lease on apps/hbase/data/oldWALs/hostname%2C60020%2C1509533411668.default.1511981830928 (inode 607514): File is not open for writing. Holder DFSClient_NONMAPREDUCE_1409651844_1 does not have any open files.

 

It was during heavy reading - writing.

While configuring HDFS I found and set recommendation to increase HDFS parameter to:

<property>
<name>dfs.datanode.max.transfer.threads</name>
<value>16000</value>
</property>
