[jira] Created: (HBASE-2025) 0.20.2 accessed from older client

0.20.2 accessed from older client throws UndeclaredThrowableException; frustrates rolling upgrade
-------------------------------------------------------------------------------------------------
Key: HBASE-2025
URL: https://issues.apache.org/jira/browse/HBASE-2025
Project: Hadoop HBase
Issue Type: Bug
Reporter: stack
Fix For: 0.20.3
>From the list:
{code}
After upgrading HBase from 0.20.0 to 0.20.2 I am getting following error
message:
java.lang.reflect.UndeclaredThrowableException

This is happening for the following line in my code:
this.table = new HTable(new HBaseConfiguration(), tableName);
This used to work flawlessly before, so seems like something changed in
HBaseConfiguration, may be? I am looking into this, but any pointers would
be greatly appreciated.
{code}
We should figure what we broke. Try fix for 0.20.3. In future, as part of release, try accessing cluster with an older client to ensure we've not done something that would frustrate rolling upgrade.

------------------------------
+1 on applying the patch.
The sort makes it so we can't add a new method between versions because it will throw off the ids? So it seems like we can only add a new method to an interface IFF it is an override of an already-existing method?

-------------------------------------------
Wait I was wrong, you simply can't add a new method since it will change the codes.
Not so sure about backing out... Could that screw installs?

[jira] Updated: (HBASE-2025) 0.20.2 accessed from older client
throws UndeclaredThrowableException; frustrates rolling upgrade
Posted by "Andrew Purtell (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-2025?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrew Purtell updated HBASE-2025:
----------------------------------
Priority: Blocker (was: Major)
Raising priority to blocker on branch. If there's a flaw that prevents rolling upgrade we should fix it here not propagate it to another minor release.

[jira] Commented: (HBASE-2025) 0.20.2 accessed from older client
throws UndeclaredThrowableException; frustrates rolling upgrade
Posted by "Jean-Daniel Cryans (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-2025?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12795392#action_12795392 ]
Jean-Daniel Cryans commented on HBASE-2025:
-------------------------------------------
The reason why adding a method at the end of an interface doesn't work is actually in the code of HBaseRPC:
{code}
// There are no guarantees about the order in which items are returned in
// so do a sort (Was seeing that sort was one way on one server and then
// another on different server).
Arrays.sort(methods, new Comparator<Method>() {
public int compare(Method left, Method right) {
return left.getName().compareTo(right.getName());
}
});
{code}

------------------------------
Well I suppose backing out deletes will throw off codes so yeah let's not do that. But adding An override should work since it will not change codes? Don't all overrides have same code?

Jean-Daniel Cryans commented on HBASE-2025:
-------------------------------------------
So every client works on every 0.20 minor revision except for 0.20.0 since HBASE-1574 changed HRegionInterface. We have to tell our users to not do a rolling upgrade from 0.20.0
I will also investigate why a new method in the interface generates NPE.

[jira] Commented: (HBASE-2025) 0.20.2 accessed from older client
throws UndeclaredThrowableException; frustrates rolling upgrade
Posted by "Jean-Daniel Cryans (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-2025?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12795401#action_12795401 ]
Jean-Daniel Cryans commented on HBASE-2025:
-------------------------------------------
Further notes.
When we add a new method in RPC we call this:
{code}
static void addToMap(final String name, final byte code) {
if (METHODNAME_TO_CODE.containsKey(name)) {
return;
}
METHODNAME_TO_CODE.put(name, Byte.valueOf(code));
CODE_TO_METHODNAME.put(Byte.valueOf(code), name);
}
{code}
This means that put(final byte [] regionName, final Put put) and put(final byte[] regionName, final Put [] puts) share the same code. The reason it works is that once we get the name of the method we build the full signature using the name of the classes passed by the client call:
{code}
Method method =
implementation.getMethod(call.getMethodName(),
call.getParameterClasses());
{code}
This means that the NPE we get is pure luck, we could also be in a situation where the code is valid but returns the wrong method name.

-------------------------------------------
As long as new method has an already existing name in any ipc interface, you're good. The rest of the signature is then processed differently.

Jean-Daniel Cryans commented on HBASE-2025:
-------------------------------------------
I committed my patch to branch and trunk. I don't think we should remove the batch deletes, there's probably not that many people who are planning to do a rolling upgrade from 0.20.0 straight to 0.20.3 so I vote to close this issue.
