[jira] [Created] (IMPALA-9443) [DOC] Update show table stats output
Tamas Mate created IMPALA-9443:
----------------------------------
Summary: [DOC] Update show table stats output
Key: IMPALA-9443
URL: https://issues.apache.org/jira/browse/IMPALA-9443
Project: IMPALA
Issue Type: Documentation
Components: Docs
Reporter: Tamas Mate
The {{SHOW TABLE STATS}} output for HDFS tables is outdated on some doc sites or abbreviated with ellipsis. Additionally, some other tables can be broken as well, for example {{SHOW FILES IN}}. I am aware of the following pages:
- [https://impala.apache.org/docs/build/html/topics/impala_show.html]
- [https://impala.apache.org/docs/build/html/topics/impala_perf_stats.html]
{code:java}
Currently the output of an empty HDFS table looks like this:
+-------+--------+------+--------------+-------------------+--------+-------------------+-------------------------------------------------+
| #Rows | #Files | Size | Bytes Cached | Cache Replication | Format | Incremental stats | Location |
+-------+--------+------+--------------+-------------------+--------+-------------------+-------------------------------------------------+
| -1 | 15 | 149B | NOT CACHED | NOT CACHED | TEXT | false | hdfs://localhost:20500/test-warehouse/test |
+-------+--------+------+--------------+-------------------+--------+-------------------+-------------------------------------------------+
