    Description

      Impala saves Timestamp as 92 bit value, while supporting Timestamp for Kudu using unixtime_micros (i.e. int64).  This causes different hash values being used when calling Insert() and Find() for bloom filter.

      Impala should generate timestamp bloom filters for Kudu by using 64 bit unixtime_micros.
