Keith Turner created ACCUMULO-2051:
--------------------------------------
Summary: Can write to accumulo when using viewfs://
Key: ACCUMULO-2051
URL: https://issues.apache.org/jira/browse/ACCUMULO-2051
Project: Accumulo
Issue Type: Sub-task
Reporter: Keith Turner
Fix For: 1.6.0
See parent ticket for env info. Seeing the following error which prevents
writing from the walog. Its easy to work around by changing the call from
FileSystem.getDefaultReplication() to FileSystem.getDefaultReplication(Path
path). However this easy work around will probably break Hadoop 1.0 support.
