Subject CorruptedSnapshotException Taking Snapshot Of Table With Large Number Of Files
Date Mon, 19 Mar 2018 17:16:01 GMT
Hi,

We are running on HBase 1.4.0 on an AWS EMR/HBase cluster.

We have started seeing the following stacktrace when trying to take a
snapshot of a table with a very large number of files (12000 regions and
roughly 360000 - 400000 files). The number of files should go down as we
haven't been compacting for a while for other operational reasons and are
now running it. But I'd to understand why our snapshots are failing with
the following:
