Hello Gang,
I've been investigating this issue.
This should no longer be an issue with ANTL4 (and ANTLR3 is long since
stopped seeing development circa 2014). However, ANTL4 is not fully
backwards compatible with ANTL3. In particular, ANTL4 changes how it
approaches "rewrite rules" operations.
Hello Gang,
I am investigating HIVE-23172 and I am having a problem addressing this
because I am getting the following error from compiling the grammar:
hive-parser: Compilation failure
