--------------------------------
Summary: Increase the minimum split size and add a classpath to
hadoop tools
Key: TAJO-1872
URL: https://issues.apache.org/jira/browse/TAJO-1872
Project: Tajo
Issue Type: Task
Components: conf and scripts
Reporter: Jihoon Son
Fix For: 0.11.0
The current minimum split size is 1 byte. This can cause a wrong behaviour when
the underlying file system gives the wrong block size.
For example, s3a file system sometimes returns 0, so tajo creates a split for
each byte as follows.
