[11/50] incubator-impala git commit: Print last 50 lines of log if data loading fails.

[ta...@apache.org]

Print last 50 lines of log if data loading fails.

The 20 lines we dump currently are often not enough to
diagnose a failure quickly. Increasing to 50 lines.

Printing 50 lines is also consistent with our run-step
script which also prints 50 lines.
