> The issue is on MaprFS file system. Probably, can be reproduced on HDFS, but not sure.

> We have observed in td-agent log whenever webhdfs plugin call to flush events its calling
append instead of create file on maprfs by communicating with webhdfs. We need to modify this
plugin to create file and then append data to the file as manually creating file is not a
solution as lot of log events write to Filesystem they need to rotate on timely basis.
