----------------------------------------
[~spena], yes, i can still reproduce that on the current master. You can just
save the commands in a q file. If you run that with TestCliDriver, you will have
{code}
STAGE DEPENDENCIES:
Stage-0 is a root stage
STAGE PLANS:
Stage: Stage-0
Fetch Operator
limit: -1
Processor Tree:
TableScan
alias: unencryptedtable
Statistics: Num rows: 2 Data size: 22 Basic stats: COMPLETE Column
stats: NONE
Select Operator
expressions: key (type: string), value (type: string)
outputColumnNames: _col0, _col1
Statistics: Num rows: 2 Data size: 22 Basic stats: COMPLETE Column
stats: NONE
ListSink
{code}
This is correct.
However, if you run that with TestEncryptedHDFSCliDriver, you will have
{code}
STAGE DEPENDENCIES:
Stage-0 is a root stage
STAGE PLANS:
Stage: Stage-0
Fetch Operator

Processor Tree:
TableScan
alias: unencryptedtable
Statistics: Num rows: 1 Data size: 24 Basic stats: COMPLETE Column

This is not correct. If you look into more details, you will find that analyze
table statement never works. Thanks.

> URL: https://issues.apache.org/jira/browse/HIVE-10938
> Project: Hive
> Issue Type: Bug
> Reporter: Pengcheng Xiong
>
> To reproduce, in recent q test environment, create a q file
> {code}
> drop table IF EXISTS unencryptedTable;
> create table unencryptedTable(key string, value string);
> insert into table unencryptedTable values
> ('501', 'val_501'),
> ('502', 'val_502');
> analyze table unencryptedTable compute statistics;
> explain select * from unencryptedTable;
> {code}
> Then run with TestEncryptedHDFSCliDriver.
> analyze table will generate a MapRed task and a StatsTask. The MapRed task
> will fail silently without generating the stats, e.g., numRows for the table.
> And the following StatsTask can not read any results. This will fail not only
> for encrypted tables but also non-encrypted one as shown above.
