---------------------------------
Summary: Java tests fail when starting MiniKuduCluster with log
block manager
Key: KUDU-2507
URL: https://issues.apache.org/jira/browse/KUDU-2507
Project: Kudu
Issue Type: Bug
Components: java
Reporter: Andrew Wong
When running Java tests that use a MiniKuduCluster on linux machines that don't
support hole punching, they will use the LBM by default, but fail to start the
cluster upon attempting to do the hole punching.

F0717 08:36:53.926518 22774 master_main.cc:81] Check failed: _s.ok() Bad
status: IO error: Could not create new FS layout: Unable to create directory
manager: could not create new data directories: Error during hole punch test.
The log block manager requires a filesystem with hole punching support such as
ext4 or xfs. On el6, kernel version 2.6.32-358 or newer is required. To run
without hole punching (at the cost of some efficiency and scalability),
reconfigure Kudu with --block_manager=file. Refer to the Kudu documentation for
more details. Raw error message follows: Unexpected pre-punch file size for
