Hello Thomas Tauber-Marshall, Kurt Deschler, Joe McDonnell, Impala Public
Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/17145
to look at the new patch set (#6).
Change subject: IMPALA-10552: External Frontend CTAS support
......................................................................
IMPALA-10552: External Frontend CTAS support
- Adds the concept of an external staging dir to HdfsTableSink
- This allows an external to specify the destination of the
sink
- When this is set, the external frontend is responsible for
for moving and managing the results
- Any DDL related operations are assumed to be handled by
the external frontend
- External frontends may optionally supply a partition
depth which acts as a hint to skip a certain number of
partitions while creating directories for partitions. This
is for when the external frontend has pre-created a
certain number of the directories in staging (usually the
static portion of a partition specification)/
- Modifies delta/base naming to include 0 prefix padding to
match Hive for dynamic partitioning detection
- External frontends are responsible for doing authorization
checks against the staging directory and it is assumed the
external frontend service is not exposed directly to users.
