dvitiiuk opened a new pull request #3255: URL: https://github.com/apache/ambari/pull/3255
## What changes were proposed in this pull request? The problem was in null interpretation for BINARY fields during working via phoenix with hbase. Null value was being wrote as array of zero bytes, so after reading of this value we got not null, but array of zero bytes. Now array of zero bytes is being interpreted as null. As result we shouldn't generate UUIDs which contain only zero bytes. Also made some fixes in ambari datasource.js for grafana. ## How was this patch tested? Manual test: - created kafka-based and usual storm topologies and checked that all appropriate metrics are being displayed. - run metrics tests locally. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
