J.B. Langston updated CASSANDRA-4568:
-------------------------------------
Labels: datastax_qa (was: )
> countPendingHints JMX operation is returning garbage for the key
> ----------------------------------------------------------------
>
> Key: CASSANDRA-4568
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4568
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.0.10, 1.1.2
> Reporter: J.B. Langston
> Priority: Minor
> Labels: datastax_qa
>
> countPendingHints JMX operation should return a map from key: endpoint IP
> address to value: number of pending hints. It is returning garbage for the
> key (looks like binary data concerning the hint itself). The value looks
> correct.
> Steps to reproduce:
> 1) Set up a two-node cluster.
> 2) Disable gossip on the second node.
> `nodetool ring` output from node 1:
> Address DC Rack Status State Load
> Effective-Ownership Token
>

> 192.168.1.130 datacenter1 rack1 Down Normal 6.67 KB
> 100.00% 85070591730234615865843651857942052864
> 3) While the second node is still down, create a keyspace with RF=2 and a CF
> within this keyspace. Then insert two records into the CF:
> Connected to Test Cluster at 192.168.1.162:9160.
> [cqlsh 2.2.0 | Cassandra 1.1.2 | CQL spec 2.0.0 | Thrift protocol 19.32.0]
> Use HELP for help.
> cqlsh> create KEYSPACE demo WITH strategy_class = 'SimpleStrategy' AND
> strategy_options:replication_factor = 2;
> cqlsh> use demo;
> cqlsh:demo> create table users (username varchar primary key, password
> varchar);
> cqlsh:demo> insert into users (username, password) values (scott, tiger);
> cqlsh:demo> insert into users (username, password) values (root, password);
> 4) Use a JMX client to execute the countPendingHints operation:
> jblangston:~ jblangston$ java -jar cmdline-jmxclient-0.10.3.jar -
> localhost:7199 org.apache.cassandra.db:type=HintedHandoffManager
> countPendingHints
> 08/22/2012 14:21:37 -0500 org.archive.jmx.Client countPendingHints: {@B^h ??
> ?[b??scottdemoscott?????password?ߞHtigerdemoF
> ?P?? ?[b??rootdemoroot?????password?ߞ?Wpassworddemo=2}
> 5) Notice the output. The value (2) is correct but the key is garbage
> instead of an endpoint IP address.
