[jira] [Created] (ACCUMULO-476) java.lang.ClassCastException:
com.mapr.fs.MapRFileSystem cannot be cast to
org.apache.hadoop.hdfs.DistributedFileSystem
java.lang.ClassCastException: com.mapr.fs.MapRFileSystem cannot be cast to org.apache.hadoop.hdfs.DistributedFileSystem
-----------------------------------------------------------------------------------------------------------------------
Key: ACCUMULO-476
URL: https://issues.apache.org/jira/browse/ACCUMULO-476
Project: Accumulo
Issue Type: Bug
Components: logger, master, tserver
Affects Versions: 1.4.0
Environment: Accumulo 1.4 rc 2 on mapr m5.
Reporter: Todd Stavish
Assignee: Eric Newton
>From Keith Turner on the accumulo user group:
I looked at the code and its just simply cast to a
DistributedFileSystem inorder to check if HDFS is in safe mode. It
should do an instanceof operation and then do the case. Would you
mind opening a ticket about this?

Keith Turner commented on ACCUMULO-476:
---------------------------------------
I will try to create a functional test that uses the LocalFileSystem instead of DistributedFileSystem. Hopefully that will reproduce this and maybe find other issues.
