---------------------------------------
Summary: Improve error messages for REFRESH TABLE METADATA command
Key: DRILL-4544
URL: https://issues.apache.org/jira/browse/DRILL-4544
Project: Apache Drill
Issue Type: Improvement
Components: Metadata
Reporter: Arina Ielchiieva
Assignee: Arina Ielchiieva
Priority: Minor
Fix For: 1.7.0
Improve the error messages thrown by REFRESH TABLE METADATA command:
In the first case below, the error is maprfs.abc doesn't exist. It should throw
a Object not found or workspace not found. It is currently throwing a non
helpful message;
0: jdbc:drill:> refresh table metadata maprfs.abc.`my_table`;
--------------------+
ok summary
--------------------+
false Error: null
--------------------+
1 row selected (0.355 seconds)
In the second case below, it says refresh table metadata is supported only for
single-directory based Parquet tables. But the command works for nested
multi-directory Parquet files.
0: jdbc:drill:> refresh table metadata maprfs.vnaranammalpuram.`rfm_sales_vw`;
-----------+
ok summary
-----------+
false Table rfm_sales_vw does not support metadata refresh. Support is
currently limited to single-directory-based Parquet tables.
