Subject [jira] [Commented] (FALCON-1343) validation of read/write endpoints is not reliable
Date Tue, 15 Sep 2015 14:42:45 GMT

    [ https://issues.apache.org/jira/browse/FALCON-1343?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14745544#comment-14745544

Balu Vellanki commented on FALCON-1343:

[~peeyushb] /tmp always exists in HDFS, not so for /temp. For readonly, Falcon do not need
to create any files. Falcon just has to verify that user can connect to namenode. So /tmp
is better option.

> A read/write endpoint is currently validated by creating a filesystem with the endpoint
> {code}
>             HadoopClientFactory.get().createProxiedFileSystem(conf);
> {code}
> I confirmed with a HDFS team member that it is not sufficient validation.  Ideally check
if the end user has access by doing atleast a list /tmp call after creating proxiedFileSystem.
