> 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.
> -----------+
> 1 row selected (0.418 seconds)
> 0: jdbc:drill:>
