Matthew Jacobs has uploaded a new patch set (#2). Change subject: IMPALA-5137: Support Kudu UNIXTIME_MICROS as Impala TIMESTAMP ......................................................................
IMPALA-5137: Support Kudu UNIXTIME_MICROS as Impala TIMESTAMP Adds Impala support for TIMESTAMP types stored in Kudu. Impala stores TIMESTAMP values in 96-bits and has nanosecond precision. Kudu's timestamp is a 64-bit microsecond delta from the Unix epoch (called UNIXTIME_MICROS), so a conversion is necessary. TODO: As of now, this only supports writing TIMESTAMPs to Kudu. Reading will require the Kudu client to return UNIXTIME_MICROS in a padded slot for Impala. In the meantime, an exception is thrown in the FE when attempting to read from a TIMESTAMP from a Kudu table. Some tests were added using the python Kudu client to read the results, but more tests will be added when Impala can read as well.
