1. I found this issue (https://issues.apache.org/jira/browse/TAJO-826) which has a comment that we should remove all JSON related part from TajoCli. Does it mean that we want to make tsql support SQL queries only and create a separate client dedicated for JSON queries?
2. While trying to fix a minor bug in JSON parsing, I found that any of changes I made to Expr.java had no effect on tsql behavior. Does it read a pre-compiled jar file from somewhere else? What should I do to test my Expr changes? Thanks, Jaewoong
