I just uploaded a preview of a code change for IMPALA-6052, which changes the HDFS directory locations for Impala test data: https://gerrit.cloudera.org/#/c/8260/ Summary of the change below.
This change would require all developers to reload test data, so I wanted to start a discussion about the timing of this change. In particular, does a change like this belong in a point release (2.12)? Are there any concerns about going forward with this change for 2.12? Thanks, Joe Test tables will now be organized into database directories rather than being at the top level of /test-warehouse. The new format matches the default placement of a table when LOCATION is not specified. e.g. Table: functional.alltypes Old: /test-warehouse/alltypes New: /test-warehouse/functional.db/alltypes Table: functional_parquet.alltypes Old: /test-warehouse/alltypes_parquet New: /test-warehouse/functional_parquet.db/alltypes Before this change, /test-warehouse has 900+ subdirectories. After the change, it has about 60. This should make it easier to navigate our HDFS directories.
