Hi folks, please pardon me for re-opening this issue. I am wondering if there is a better way to disable "appends" for 0.19.1 We coudld set the config parameter dfs.support.append to false in hadoop-defaults.xml. This means that a default installation of hadoop will not support "appends". However, for people that are testing their apps (not in production), it gives them an easy way to test their apps.
Dhruba, folks who want to test with append can use 0.19.0.
There could be big-and-large warning message associated with the dfs.support.append parameter warning people to the fact that there could be data corruption if they set that flag to true.
The uploaded patch creates a dfs.support.append config entry but doesn't seem to use it in the append method to affect it's behavior. What am I missing?
I am re-opening this issue because I am not sure whether this approach was considered. If it was considered and was shot down, please let me know why and u can close this issue.
I think this should be a new Jira that could be fixed in 0.19.2. If you agree, please close this and open a new Jira.
