-----------------------------------
Summary: The error message in TimelineSchemaCreator is not enough
to find out the error.
Key: YARN-7128
URL: https://issues.apache.org/jira/browse/YARN-7128
Project: Hadoop YARN
Issue Type: Bug
Affects Versions: 3.0.0-beta1
Reporter: Jinjiang Ling
Assignee: Jinjiang Ling
When I run the schema creator tool of timeline service v2, then an error
happened with the error message below:

17/08/30 16:04:18 INFO zookeeper.ClientCnxn: Session establishment complete on
server zdh175/10.43.183.175:2181, sessionid = 0x15e0d065a330019, negotiated

17/08/30 16:04:18 WARN util.HeapMemorySizeUtil:

17/08/30 16:04:18 ERROR storage.TimelineSchemaCreator: Error in creating hbase
tables: java.lang.reflect.InvocationTargetException
17/08/30 16:04:18 WARN storage.TimelineSchemaCreator: Schema creation finished
with the following exceptions
17/08/30 16:04:18 WARN storage.TimelineSchemaCreator:

But I can't tell which error caused this exception with message.
Then I find it only print the exception message in TimelineSchemaCreator
{code}
try {
......
} catch (IOException e) {
LOG.error("Error in creating hbase tables: " + e.getMessage());
exceptions.add(e);
}
{code}
I change it like this
{code}
try {
......
} catch (IOException e) {
LOG.error("Error in creating hbase tables: ", e);
exceptions.add(e);
}
{code}
finally, I get the detail of this error, and it's caused by a directory of
hbase not created.

As the exception message is not enough to find out the error, so I think print
all the information of the exception in TimelineSchemaCreator is better.
