Ying Zheng updated FALCON-1984:
-------------------------------
Description:
We require the user to choose either HBase or BDB as titan storage backend,
which is not set by default in startup.properties. The current Falcon only
shows the following error in the log if the user doesn't configure the storage
backend and start falcon with default startup.properties. This is not intuitive
for the user to understand the server start error. Should provide proper hint
and documentation.
