----------------------------------
Summary: LogicalPlanVerifier should check not supported type in
file formats
Key: TAJO-1226
URL: https://issues.apache.org/jira/browse/TAJO-1226
Project: Tajo
Issue Type: Improvement
Components: planner/optimizer
Reporter: Hyunsik Choi
Fix For: 0.9.1
*Problem*
There are a variety of file formats in Hadoop eco systems. BTW, they have
different type supports. For example, RCFile supports DATE type, but Parquet
does not support DATE. Users can use not supported data types in a specified
file format for writing tables.
But, current Tajo does not check available data types for each file format. So,
if a user specifies not supported types in his table for writing, a runtime
error will occur while a query is running.
*Solution*
We should check not supported data type in logical plan verification phase.
