Hitesh Shah commented on TEZ-2805:
----------------------------------
To be clear, the same query against the same dataset sometimes works but
sometimes fails with this error?
>From the lzoinputformat codebase, it seems like indexes is only setup properly
>when listStatus() is called. Is there any other place where indices is filled
>up? Would it be possible for you to add a log there and print the stack trace
>so that using 2 separate logs ( one from a failed and one from a successful
>run ), we can look at what is different? Also, maybe add a log for which
>filename causes an NPE to be thrown?
