--------------------------------
Summary: Use pseudo-injection buffer in function implementation
when it requires temporary buffer
Key: DRILL-422
URL: https://issues.apache.org/jira/browse/DRILL-422
Project: Apache Drill
Issue Type: Bug
Reporter: Jinfeng Ni
In DRILL-379, the code uses a wrapper buffer over a java byte array for
temporary buffer used by some string functions. However, such wrapper buffer
will use big endian, different from Drill's native little endian. This may not
be a big issue for string, but could cause serious issues for other types.
In stead, we should use an approach where the buffer is provided from Drill
fragment context through pseudo-injection to get the access to buffers, and the
context will be responsible for cleaning things up.
