[jira] Created: (HBASE-739) HBaseAdmin.createTable() using old
HTableDescription doesn't work
HBaseAdmin.createTable() using old HTableDescription doesn't work
-----------------------------------------------------------------
Key: HBASE-739
URL: https://issues.apache.org/jira/browse/HBASE-739
Project: Hadoop HBase
Issue Type: Bug
Components: client
Affects Versions: 0.2.0
Reporter: Sebastien Rainville
Priority: Minor
The following test case (see below) illustrate what used to work in branch 0.1 and that doesn't anymore. testTruncateInTrunk() shows how I got it to work again. I get this error now when trying the old code but using trunk:

[jira] Issue Comment Edited: (HBASE-739) HBaseAdmin.createTable()
using old HTableDescription doesn't work

------------------------------------------------------------
I think I've really fixed it this time. I added a default constructor to UnmodifyableHTableDescriptor, which I should have done in the last patch (this all goes in the same vein of making UnmodifyableHTableDescriptor serializable).
I found that Eclipse really confused the testing process - I definitely ran the test with and without the default constructor, sometimes succeeding and sometimes failing. Running the test on the command-line was much more useful and straightforward, and I'd recommend doing that instead (at least for this test). Here's how you can run just that test on the command-line:
Add the following to your build.xml:
{code}
<target name="ensure-test-name" unless="test">
<fail message="You must run this target with -Dtest=TestName"/>
</target>
<target name="runtest" description="Runs the test you specify on the command line with -Dtest=" depends="compile, ensure-test-name">
<junit printsummary="withOutAndErr" fork="yes">
<classpath refid="test.classpath" />
<formatter type="plain" usefile="false"/>
<batchtest>
<fileset dir="${src.test}">
<include name="**/${test}.java"/>
</fileset>
</batchtest>
</junit>
</target>
{code}
Start HBase, make sure TestHbase739.java is added, "mytable" exists, etc, and then enter:
{code}
ant clean jar compile-test runtest -Dtest=TestHbase739
{code}
Without the attached patch, hbase-739_v2.patch, this should fail (it might say "Build Successful", but check the actual junit output). After adding the attached patch, this should succeed (at least it did for me, when doing this process on a fresh copy of HBase).
Let me know if this is still generating errors.

[jira] Updated: (HBASE-739) HBaseAdmin.createTable() using old
HTableDescription doesn't work
Posted by "Izaak Rubin (JIRA)" <ji...@apache.org>.

Izaak Rubin updated HBASE-739:
------------------------------
Attachment: TestHbase739.java
I'm attaching the JUnit test I used for testing the issue. The code is almost identical to that posted by Sebastien, except I've added lines that disable the table before dropping.

[jira] Updated: (HBASE-739) HBaseAdmin.createTable() using old
HTableDescription doesn't work
Posted by "Izaak Rubin (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-739?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Izaak Rubin updated HBASE-739:
------------------------------
Attachment: hbase-739.patch
I've investigated this issue and have several things to report. Sebastien, I wasn't able to replicate the exact error you gave in the issue description. I did, however, get an error under the same circumstances (for testTruncateInBranch_0_1, although my error was a SocketTimeoutException). Also, I should point out that the testing code you posted doesn't disable the table before dropping it, which causes other problems.
The issue, or at least the one that I experienced with SocketTimeoutException, was that UnmodifyableHTableDescriptor did not serialize. The server could not see the UnmodifyableHTableDescriptor class because it was package-protected and resides in hbase.client. The solution, and the attached patch, merely involves adding the word "public" to the UnmodifyableHTableDescriptor class declaration. The server can now see the class and serialize it.

[jira] Updated: (HBASE-739) HBaseAdmin.createTable() using old
HTableDescription doesn't work
Posted by "Izaak Rubin (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-739?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Izaak Rubin updated HBASE-739:
------------------------------
Attachment: hbase-739_v2.patch
I think I've really fixed it this time. I added a default constructor to UnmodifyableHTableDescriptor, which I should have done in the last patch (this all goes in the same vein of making UnmodifyableHTableDescriptor serializable).
I found that Eclipse really confused the testing process - I had definitely run the test with and without the default constructor, sometimes succeeding and sometimes failing. Running the test on the command-line was much more useful and straightforward, and I'd recommend doing that instead (at least for this test). Here's how you can run just that test on the command-line:
Add the following to your build.xml:
{code}
<target name="ensure-test-name" unless="test">
<fail message="You must run this target with -Dtest=TestName"/>
</target>
<target name="runtest" description="Runs the test you specify on the command line with -Dtest=" depends="compile, ensure-test-name">
<junit printsummary="withOutAndErr" fork="yes">
<classpath refid="test.classpath" />
<formatter type="plain" usefile="false"/>
<batchtest>
<fileset dir="${src.test}">
<include name="**/${test}.java"/>
</fileset>
</batchtest>
</junit>
</target>
{code}
Start HBase, make sure TestHbase739.java is added, "mytable" exists, etc, and then enter:
{code}
ant clean jar compile-test runtest -Dtest=TestHbase739
{code}
Without the attached patch, hbase-739_v2.patch, this should fail (it might say "Build Successful", but check the actual junit output). After adding the attached patch, this should succeed (at least it did for me, when doing this process on a fresh copy of HBase).
Let me know if this is still generating errors.

stack commented on HBASE-739:
-----------------------------
I applied Izaak's patch (You should be able to use an UnmodifableHTD in the manner Sebastien is trying to use it above).
Sebastien, if Izaak's patch fixes your issue, please close this issue; otherwise, provide more info. Thanks.

[jira] Commented: (HBASE-739) HBaseAdmin.createTable() using old
HTableDescription doesn't work
Posted by "Jim Kellerman (JIRA)" <ji...@apache.org>.

Jim Kellerman commented on HBASE-739:
-------------------------------------
The API for 0.2.0 is not backward compatible with 0.1.x
This was a deliberate decision since the new features of 0.2.0 required big API changes, and some of the 0.1.x behavior cannot be supported with a compatibility layer.

Sebastien Rainville commented on HBASE-739:
-------------------------------------------
Actually, I'm not getting the exact same error as before. I'm getting java.net.SocketTimeoutException directly... and before I was getting a java.lang.reflect.InvocationTargetException CAUSED BY java.net.SocketTimeoutException.
It sounds like I'm getting the same error as you were seeing Isaac but somehow you got rid of it and not me. (and yes I updated my code and I see that you patch has been applied) So, your patch resolved the java.lang.reflect.InvocationTargetException but not the java.net.SocketTimeoutException.

Izaak Rubin commented on HBASE-739:
-----------------------------------
Yeah, I'm also getting the same error again. Its weird, the code hasn't changed since Friday! I'm looking back into it again.

[jira] Updated: (HBASE-739) HBaseAdmin.createTable() using old
HTableDescription doesn't work
Posted by "Sebastien Rainville (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-739?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sebastien Rainville updated HBASE-739:
--------------------------------------
Attachment: master.log
TestTruncate2.java
TEST-org.apache.hadoop.hbase.TestTruncateIsaak.txt
I'm still getting the same error. I attached the logs of the test case and the master in debug mode. I modified the test case so it creates the test table automatically. I'm not so worried about this issue but it might uncover something worse underneath. And about the missing disableTable()... it was a copy paste error.
