cassandra getendpoints with partition key has space


my partition keys are id(int) and name(text). Below command works fine until there is no space in name(text). nodetool getendpoints test testtable2 1:aaa;

if am using nodetool getendpoints test testtable2 3:aac cc; it throws an error as :nodetool: getendpoints requires keyspace, table and partition key arguments See 'nodetool help' or 'nodetool help '.

i got token by executing SELECT id,name, token(id,name) FROM test.testtable2 where name='aac cc'AND id=3; and tried to search nodetool getendpoints test testtable2 -7072928299163215694; error: For input string: "-7072928299163215694" -- StackTrace -- java.lang.NumberFormatException: For input string: "-7072928299163215694"

how can i search if partition key (name) has space?


Solution

  • This is an issue of nodetool command.

    I have modified the nodetool script and create getendpoints script to support getendpoints with partition key has space

    Here is the getendpoints code :

          $JVM_ARGS \
          org.apache.cassandra.tools.NodeTool -p $JMX_PORT getendpoints $KS $CF "$KEY"
    

    Put getendpoints file under $CASSANDRA_HOME/bin directory.

    Now you can run this file with nodetool argument,along with below argument

    getendpoints -k keyspace_name -t table_name key
    

    Example :

    getendpoints -k test -t testtable2 3:aac cc
