[jira] [Commented] (CASSANDRA-6529) sstableloader shows no progress or errors when pointed at a bad directory

["Tyler Hobbs (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-6529?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13860335#comment-13860335 ] 

Tyler Hobbs commented on CASSANDRA-6529:
----------------------------------------

It would be nice to have an error message instead of a stack trace:

{noformat}
~/cassandra $ bin/sstableloader /foo/bar -d 127.0.0.1
Exception in thread "main" java.lang.RuntimeException: Could not retrieve endpoint ranges:

Can we wrap the describe_ring() call in a try/catch for InvalidRequestException and just print the "why" attribute and a brief message that suggests checking the usage?

> With sstableloader, the source directory is supposed to be in the format {{<keyspace_name>/<table_name>/}}.  If you incorrectly just put the sstables in a {{<keyspace_name>/}} directory, the sstableloader process will not show any progress, errors, or other output, it will simply hang.
