Subject [jira] [Updated] (CASSANDRA-12279) nodetool repair hangs on non-existant table
Date Fri, 19 Aug 2016 06:10:20 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-12279?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Masataka Yamaguchi updated CASSANDRA-12279:
-------------------------------------------
    Attachment: org_result_example.txt
                new_result_example.txt
                CASSANDRA-12279-trunk.patch

This happens because the method “parseOptinalTables” in src/java/org/apache/cassandra/tools/NodeTool.java
does not confirm that the given keyspace has the given table.
The method “parseOptinalTables” is also used in some nodetool commands such as src/java/org/apache/cassandra/tools/nodetool/Cleanup.java,
src/java/org/apache/cassandra/tools/nodetool/Compact.java and so on, and Java error happens
when those commands are used with no-existent table name given, while they do not hang. 

I have reimplemented parseOptionalTables so that it confirms that the given keyspace has the
given table, and I will send the patch.
Please review it.

> If nodetool repair is called with a table that does not exist, ist hangs infinitely without
any error message or logs.
> E.g.
> nodetool repair foo bar
> Keyspace foo exists but table bar does not
