> When we store timestamps (for example as part of the row key or part of the
> column name for an event), the bytes are used as is without any encoding. If
> the byte value happens to contain a separator character we use (e.g. "!" or
> "="), it causes a parse failure when we read it.
> I came across this while looking into this error in the timeline reader:
> {noformat}
> 2016-05-17 21:28:38,643 WARN
> org.apache.hadoop.yarn.server.timelineservice.storage.common.TimelineStorageUtils:
> incorrectly formatted column name: it will be discarded
> {noformat}
> I traced the data that was causing this, and the column name (for the event)
> was the following:
> {noformat}
> i:e!YARN_RM_CONTAINER_CREATED=\x7F\xFF\xFE\xABDY=\x99=YARN_CONTAINER_ALLOCATED_HOST
> {noformat}
> Note that the column name is supposed to be of the format (event
> id)=(timestamp)=(event info key). However, observe the timestamp portion:
> {noformat}
> \x7F\xFF\xFE\xABDY=\x99
> {noformat}
> The presence of the separator ("=") causes the parse error.
