> We hit errors in TT due to long classpath value. One example is Oozie try=
ing to start a hive job, and it fails with the following error:
>  java.io.IOException: Command exceeds the OS command length limit: 8192, =
command: "set CLASSPATH=3D"=E2=80=A6.
> The classpath includes Hadoop Core + Hive Jars which are in the distribut=
ed cache. This is causing the classpath to be too long giving the error abo=
ve. 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.
