At runtime I changes my dependencies and I started getting an error in
Twill. I was seeing an NPE at the following line.
org.apache.twill.yarn.YarnTwillRunnerService.getApplicationId(YarnTwillRunnerService.java:542)
~[twill-yarn-0.6.0-incubating.jar:0.6.0-incubating]
Through zookeeper and twill logging, I tracked the cause down to the
following data being in zookeeper.
The following path :
/fluo-app-phrasecount/instances/2e0b9fe4-6e1c-4ecc-a454-d821e8453cb9
had the following data :
{"members":{"data":{"appId":1,"appIdClusterTime":1465862775942,"containerId":"container_1465862775942_0001_01_000001"}}}
When I run with a set of dependencies that works, I see the following data
in zookeeper. This has a root of data in the json as opposed to the root
of members.
{"data":{"appId":1,"appIdClusterTime":1465866930685,"containerId":"container_1465866930685_0001_01_000001"}}
Could someone help me locate the code that sets the value of
/fluo-app-phrasecount/instances/2e0b9fe4-6e1c-4ecc-a454-d821e8453cb9 in
zookeeper? If I can locate that code, maybe I can understand why changing
my deps changed the value in ZK to have a root of members.
Thanks,
Keith
