Description
When using BulkLoader tool (sstableloader command) to transfer data from a cluster to another,
a java.util.NoSuchElementException is thrown whenever the directory contains a "snapshot" sub directory,
and the bulk load fails.
The fix should be quite simple:
Catch any NoSuchElementException thrown in SSTableLoader#openSSTables()
The directory structure:
user@cassandrasrv01:~$ ls /var/lib/cassandra/data/Keyspace1/CF1/ Keyspace1-CF1-ib-1872-CompressionInfo.db Keyspace1-CF1-ib-1872-Data.db Keyspace1-CF1-ib-1872-Filter.db Keyspace1-CF1-ib-1872-Index.db Keyspace1-CF1-ib-1872-Statistics.db Keyspace1-CF1-ib-1872-Summary.db Keyspace1-CF1-ib-1872-TOC.txt Keyspace1-CF1-ib-2166-CompressionInfo.db Keyspace1-CF1-ib-2166-Data.db Keyspace1-CF1-ib-2166-Filter.db Keyspace1-CF1-ib-2166-Index.db Keyspace1-CF1-ib-2166-Statistics.db Keyspace1-CF1-ib-2166-Summary.db Keyspace1-CF1-ib-2166-TOC.txt Keyspace1-CF1-ib-5-CompressionInfo.db Keyspace1-CF1-ib-5-Data.db Keyspace1-CF1-ib-5-Filter.db Keyspace1-CF1-ib-5-Index.db Keyspace1-CF1-ib-5-Statistics.db Keyspace1-CF1-ib-5-Summary.db Keyspace1-CF1-ib-5-TOC.txt ... snapshots
The stacktrace:
user@cassandrasrv01:~$ ./cassandra/bin/sstableloader -v --debug -d cassandrabck01 /var/lib/cassandra/data/Keyspace1/CF1/
