Subject [jira] [Commented] (CASSANDRA-4093) cli -> show keyspaces throws exception (and swallows) on column family schema_columnfamilies
Date Tue, 27 Mar 2012 23:30:27 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4093?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13240057#comment-13240057
] 

Dave Brosius commented on CASSANDRA-4093:
-----------------------------------------

I just created a brand new database directory, went into cli and did

show keyspaces;

the output finishes with this: Notice the trailing 'null'. That is caused by the exception.

    ColumnFamily: schema_columnfamilies
    "ColumnFamily definitions"
      Key Validation Class: org.apache.cassandra.db.marshal.AsciiType
      Default column value validator: org.apache.cassandra.db.marshal.BytesType
      Columns sorted by: org.apache.cassandra.db.marshal.CompositeType(org.apache.cassandra.db.marshal.AsciiType,org.apache.cassandra.db.marshal.AsciiType)
      GC grace seconds: 10368000
      Compaction min/max thresholds: 4/32
      Read repair chance: 0.0
      DC Local Read repair chance: 0.0
      Replicate on write: true
      Caching: KEYS_ONLY
      Bloom Filter FP chance: default
      Built indexes: []
      Column Metadata:
