Alejandro Abdelnur commented on HADOOP-8899:
--------------------------------------------
Suresh, my bad, I was missing the MANIFEST.MF *Class-path:* trick. Now it makes
sense, no objection. I have not look at the patch but conceptually seems OK.
Just make sure all paths to JARs listed in the *Class-path:* are relative to
the location of the manifest only JAR and there are not ../ in the paths. In
other words, all the JARs mentioned in the manifest only JAR must be in the
same directory or in a subdirectory from where the manifest only JAR is. Thx

> We hit errors in TT due to long classpath value. One example is Oozie trying

> java.io.IOException: Command exceeds the OS command length limit: 8192,
> command: "set CLASSPATH="….
> The classpath includes Hadoop Core + Hive Jars which are in the distributed
> cache. This is causing the classpath to be too long giving the error above. A
> viable long term fix is to generate a temporary JAR file in the task cache
> directory which includes all elements in the long classpath, and then provide
> this as the "-classpath" argument for the JVM to be spawned. This is gated
> for Windows only.
