LateLastContact test is an ugly hack
------------------------------------
Key: ACCUMULO-526
URL: https://issues.apache.org/jira/browse/ACCUMULO-526
Project: Accumulo
Issue Type: Bug
Components: test
Reporter: Eric Newton
Assignee: Eric Newton
Priority: Minor
The LateLastContact attempts to find troubled tservers by noticing that they
are failing to respond to status requests. If a server does not report status,
the master attempts to kill it by removing the zookeeper lock.
The way the current test works, is that it creates a fake lock using zkCli.sh,
which is not always present. It isn't really creating a proper entry in
zookeeper anyhow. It should be re-written to use java code to create a proper
entry.
Reported by Keys Botzum:
MapR does not normally install a full zookeeper install on each node. Instead
we install a zookeeper "client" on each node which is basically the zookeeper
JAR file - /opt/mapr/lib/zookeeper-3.3.2.jar. If I set ZOOKEEPER_HOME to
/opt/mapr/lib almost everything works fine since Accumulo seems to only need
the JAR file at that location. The one exception is
the stress.weird.LateLastContact which directly references zkClient.sh (in
stress/weird.py) which isn't part of the MapR install.
