Error occurred during initialization of VM The size of the object heap + VM data exceeds the maximum representable size org.apache.flume.node.Application --conf-file=/usr/local/flume/conf/flume.conf --name agent

Could not find the main class: occurred. Program will exit.
my agent configuration is as follows:
agent1.sources = tail
agent1.channels = memoryChannel
agent1.sinks = sink1
agent1.sources.tail.type = exec
agent1.sources.tail.command = tail -f /usr/local/jarsfortest/LogsForTest/generatingLogs-app.logs
agent1.sources.tail.channels = memoryChannel
agent1.sinks.sink1.type = org.apache.flume.sink.hbase.HBaseSink
agent1.sinks.sink1.channel = memoryChannel
agent1.sinks.sink1.table = testFlume
agent1.sinks.sink1.columnFamily = log
agent1.sinks.sink1.serializer = org.apache.flume.sink.hbase.RegexHbaseEventSerializer
agent1.sinks.sink1.serializer.regex = [a-zA-Zo-9]*[^C][a-zA-Z0-9]*[^C][a-zA-Z0-9]*
agent1.sinks.sink1.serializer.regexIgnoreCase = true
agent1.sinks.sink1.serializer.colNames = id, no_fill_reason, bid
agent1.sinks.sink1.channel = memoryChannel
agent1.sinks.sink1.type = logger
agent1.channels.memoryChannel.type = memory
agent1.channels.memoryChannel.capacity = 100
Please Help me..
Thanks in advance

Answer 1

This looks like you have a JVM problem rather than a Flume problem. I'd check that the JAR files are not corrupt, that you haven't set max heap size too small, etc.
Whatever is on the end of this truncated message is probably a clue, the size of the object heap + VM data
Update
agent1.channels.memoryChannel.capacity = 100
That capacity looks very small. I'd remove that line and let it use the default.
