Sangjin Lee commented on YARN-6027:
-----------------------------------
OK how about this? The {{TimelineUIDConverter}} class also uses these
characters (the same ones). Can we at least standardize on one set of
definitions? With this patch we would have
{{TimelineUIDConverter#UID_DELIMETER_CHAR}} and
{{TimelineUIDConverter#UID_ESCAPE_CHAR}}, and
{{TimelineReaderUtils#DEFAULT_DELIMETER_CHAR}} and
{{TimelineReaderUtils#DEFAULT_ESCAPE_CHAR}}. Specifically my proposal is to
change the existing calls by {{TimelineUIDConverter}} to use the new constants
in {{TimelineReaderUtils}} (or simply call {{split(String)}}).

> In YARN-5585 , fromId is supported for retrieving entities. We need similar
> filter for flows/flowRun apps and flow run and flow as well.
> Along with supporting fromId, this JIRA should also discuss following points
> * Should we throw an exception for entities/entity retrieval if duplicates
> found?
> * TimelieEntity :
> ** Should equals method also check for idPrefix?
> ** Does idPrefix is part of identifiers?
