Date Mon, 15 Oct 2012 22:25:06 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2935?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13476526#comment-13476526

Thejas M Nair commented on HIVE-2935:
-------------------------------------

With concurrency=10, we see around 25 additional failures. We ran it twice with concurrency=10
and once with concurrency=100, the total number of failures happened to be same - 70, but
some of the tests that failed were unique in each run. The additional tests that failed in
one of the test runs with concurrency=10 are - 
alter3
alter_merge_stats
bucketmapjoin2
create_escape
groupby_sort_1
groupby_sort_skew_1
input_part10
join_filters_overlap
join_map_ppr
load_fs
pcr
ppd_union_view
rcfile_default_format
sample10
sort_merge_join_desc_5
sort_merge_join_desc_6
sort_merge_join_desc_7
stats0
stats11
stats18
stats_empty_dyn_part
stats_empty_partition
union22
union24
updateAccessTime

The tests have been run with HIVE-2935.2.nothrift.patch.txt .

I went through a sample of the failures, and most of them have two types of failures -
1. metadata such as numRows and rawDataSize get reported as 0 .
eg -
alter_merge_stats
bucketmapjoin2.q 
stats18.q - desc formatted stats_part partition query - missing some stats records in output
union22  - stats records missing

groupby_sort_1.q - difference in '.. rows selected' that is printed after explain .

2. DDL command failed 
example -
Error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask
(state=08S01,code=1)
Error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask
(state=08S01,code=1)
Aborting command set because "force" is false and command failed: "drop table alter_partition_format_test;"
Aborting command set because "force" is false and command failed: "!run !!{qFileDirectory}!!/alter_partition_format_loc.q"

tests-
rcfile_createas1.q.out
alter_partition_format_loc.q.out
