Christian Esken updated CASSANDRA-13264:
----------------------------------------
Description:
sstabledump can fail with NullPointerException, when not all files are present
on Disk. This behavior is frequently present on Cassandra nodes with a high
write-throughput and much disk I/O. It looks like Cassandra writes the Data
file fast, and the other files (Statistics, ...) later when it has time to do
so. This can be even a minute later. Technically it is OK for the Cassandra DB
itself, but the sstabledump tool does not handle this gracefully.
Current behavior:
- NullPointerException (see below)
Expected behavior:
- More graceful behavior, e.g. a message to STDERR
PS: This is minor priority, I may pick up the ticket myself if nobody else is
faster.
