John Vines commented on ACCUMULO-939:
-------------------------------------
Dropped memory map to 3G, tweaked ingest to {code}./accumulo
org.apache.accumulo.server.test.TestIngest --table test --rows 65536 --cols 100
--size 1024 -z 172.16.101.220:2181 --batchMemory 10000000 --batchThreads 5
--createTable {code} (halved batch writers, dropped an order of magnitude from
batch memory, and dropped size to 1K from 8k. Ran once, no issues. Ran again
after minor compaction and I had 24 log entries of the similar entries. This is
the only different one, I think-

Still running hadoop 1.0.4. Ingest DID complete though.
