Project: Flume
Issue Type: Bug
Environment: Flume 1.3.1 and Hbase 0.96.0
Reporter: Nisanth
We have Flume 1.3.1 and Hbase 0.96.0 and when tried to ingest data to HBase
using org.apache.flume.sink.hbase.AsyncHBaseSink, I am getting the error as
"The znode for the -ROOT- region doesn't exist!"
Flume config file:
hbase-agent.sources = tail
hbase-agent.sinks = sink1
hbase-agent.channels = ch1
hbase-agent.sources.tail.type = exec
hbase-agent.sources.tail.command = tail -F /opt/FlumeTesting/Demo.txt
hbase-agent.sources.tail.channels = ch1
hbase-agent.sinks.sink1.type = org.apache.flume.sink.hbase.AsyncHBaseSink
hbase-agent.sinks.sink1.channel = ch1
hbase-agent.sinks.sink1.table = demo
hbase-agent.sinks.sink1.columnFamily = cf
hbase-agent.sinks.sink1.serializer =
org.apache.flume.sink.hbase.SimpleAsyncHbaseEventSerializer
hbase-agent.sinks.sink1.serializer.payloadColumn = col1
hbase-agent.sinks.sink1.serializer.keyType = timestamp
hbase-agent.sinks.sink1.serializer.rowPrefix = 1
hbase-agent.sinks.sink1.serializer.suffix = timestamp
hbase-agent.channels.ch1.type=memory
