[jira] [Created] (HBASE-6456) Export Utility throws
ClassNotFoundException
Shengsheng Huang created HBASE-6456:
---------------------------------------
Summary: Export Utility throws ClassNotFoundException
Key: HBASE-6456
URL: https://issues.apache.org/jira/browse/HBASE-6456
Project: HBase
Issue Type: Bug
Reporter: Shengsheng Huang
Priority: Minor
The command I ran is as below:
"bin/hbase org.apache.hadoop.hbase.mapreduce.Driver export t1 ./t1"
And I got the following exceptions:
attempt_201207261322_0002_m_000000_0, Status : FAILED
Error: java.lang.ClassNotFoundException: org.apache.hadoop.hbase.util.Bytes
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
at java.security.AccessController.doPrivileged(Native Method)

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
at org.apache.hadoop.hbase.client.HTable.<init>(HTable.java:150)
at org.apache.hadoop.hbase.mapreduce.TableInputFormat.setConf(TableInputFormat.java:100)
at org.apache.hadoop.util.ReflectionUtils.setConf(ReflectionUtils.java:62)

at org.apache.hadoop.mapred.Child$4.run(Child.java:266)
at java.security.AccessController.doPrivileged(Native Method)
at javax.security.au
...
This exception can be resolved by adding hbase common jar into HADOOP_CLASSPATH. But this is an extra step for users and not so convenient.
We could add Bytes.class into dependency Jars of the MapReduce job.

-1 core tests. The patch failed these unit tests:
org.apache.hadoop.hbase.client.TestFromClientSide
org.apache.hadoop.hbase.coprocessor.TestRegionServerCoprocessorExceptionWithAbort
org.apache.hadoop.hbase.catalog.TestMetaReaderEditor
org.apache.hadoop.hbase.master.TestMasterNoCluster
org.apache.hadoop.hbase.security.access.TestZKPermissionsWatcher
{quote}
I don't think this patch has something to do with these unit test. Also, those test cases had passed at my local deployment.

[jira] [Updated] (HBASE-6456) Export Utility throws
ClassNotFoundException
Posted by "Lars Hofhansl (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-6456?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Lars Hofhansl updated HBASE-6456:
---------------------------------
Affects Version/s: (was: 0.94.2)
I see. I removed 0.94.2 as affected version then.
This is probably due to the modularization of HBase in 0.96 then, there will likely be other classes missing.

I just did that with 0.94.1RC1 (and I have done with 0.92 before) and I have never seen this problem.
