Hi Jignesh,
Not clear what's going on with your ZK, but as a starting point, the
hsync/flush feature in 205 was implemented with an on-off switch.  Make sur=
e
you've turned it on by setting  *dfs.support.append  *to true in the
hdfs-site.xml config file.

Also, are you installing Hadoop with security turned on or off?

I'll gather some other config info that should help.
