Hi, After upgrading to Cassandra 1.1.0, I am facing some issue when starting the Cassandra server.
This is the exception [2012-04-27 19:31:38,740] INFO {org.apache.cassandra.db.Memtable} - Writing Memtable-go@1431496612(656/820 serialized/live bytes, 12 ops) [2012-04-27 19:31:38,745] ERROR {org.apache.cassandra.service.AbstractCassandraDaemon} - Exception in thread Thread[FlushWriter:1,5,main] java.lang.UnsatisfiedLinkError: org.xerial.snappy.SnappyNative.maxCompressedLength(I)I at org.xerial.snappy.SnappyNative.maxCompressedLength(Native Method) at org.xerial.snappy.Snappy.maxCompressedLength(Snappy.java:316) at org.apache.cassandra.io.compress.SnappyCompressor.initialCompressedBufferLength(SnappyCompressor.java:42) at org.apache.cassandra.io.compress.CompressedSequentialWriter.<init>(CompressedSequentialWriter.java:63) at org.apache.cassandra.io.compress.CompressedSequentialWriter.open(CompressedSequentialWriter.java:34) at org.apache.cassandra.io.sstable.SSTableWriter.<init>(SSTableWriter.java:91) at org.apache.cassandra.db.ColumnFamilyStore.createFlushWriter(ColumnFamilyStore.java:1848) at org.apache.cassandra.db.Memtable.writeSortedContents(Memtable.java:281) at org.apache.cassandra.db.Memtable.access$600(Memtable.java:48) at org.apache.cassandra.db.Memtable$5.runMayThrow(Memtable.java:318) at org.apache.cassandra.utils.WrappedRunnable.run(WrappedRunnable.java:30) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) This issue comes from snappy-java-1.0.4.1 library and it might be because it uses a native library (libsnappyjava.so) and there are some issues when it try to load that native library in osgi environment. According to this [1] previously it didn't work with tomcat too. but they have done some hack to get it work. Does anybody know how to overcome this issue?
