> 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.
