Mohammad Kamrul Islam commented on HIVE-1511:
---------------------------------------------
Updates:
Mixed news.
I was able to resolve the failed 5 hbase test cases after this modification in
Operator.java.
Form
private transient RowSchema rowSchema;
To
private RowSchema rowSchema;
Basically I took out the transient from declaration.
Although some failed testcases with NPE are resolved, it caused other testcases
to fail. The common error message is missing of no-arg constructor.
Two such examples,
[junit] Exception in thread "main" com.esotericsoftware.kryo.KryoException:
Class cannot be created (missing no-arg constructor):
org.apache.hadoop.hive.serde2.objectinspector.StandardMapObjectInspector
[junit] Exception in thread "main" com.esotericsoftware.kryo.KryoException:
Class cannot be created (missing no-arg constructor):
org.apache.hadoop.hive.serde2.objectinspector.StandardMapObjectInspector
I know we talked about these (such as making transient or not).
Do you have any suggestion?
