------------------------------
Summary: Import tool fails with NullPointerException if clusterIds
is not initialized
Key: HBASE-12337
URL: https://issues.apache.org/jira/browse/HBASE-12337
Project: HBase
Issue Type: Bug
Reporter: Ted Yu
Assignee: Ted Yu
Flavio Pompermaier reported in this thread:
http://search-hadoop.com/m/DHED4eZ8Nk1/Error+during+HBase+import&subj=Error+during+HBase+import
Here is stack trace:
{code}
Error: java.lang.NullPointerException
at org.apache.hadoop.hbase.client.Mutation.setClusterIds(Mutation.java:331)

org.apache.hadoop.hbase.mapreduce.Import$Importer.writeResult(Import.java:180)
at org.apache.hadoop.hbase.mapreduce.Import$Importer.map(Import.java:142)

{code}
This was due to clusterIds not being initialized in setup() method:
{code}
try {
zkw = new ZooKeeperWatcher(conf, context.getTaskAttemptID().toString(),
null);
clusterIds =
Collections.singletonList(ZKClusterId.getUUIDForCluster(zkw));
} catch (ZooKeeperConnectionException e) {
{code}
Instead of throwing NullPointerException from Import$Importer, Import should
exit early with proper message and exit code.
