cassandra 1.2 fails to init snappy in freebsd

问题:

ERROR [WRITE-/10.10.35.30] 2013-06-19 23:15:56,907 CassandraDaemon.java (line 175) Exception in thread Thread[WRITE-/10.10.35.30,5,main] java.lang.NoClassDefFoundError: Could not initialize class org.xerial.snappy.Snappy     at org.xerial.snappy.SnappyOutputStream.<init>(SnappyOutputStream.java:79)     at org.xerial.snappy.SnappyOutputStream.<init>(SnappyOutputStream.java:66)     at org.apache.cassandra.net.OutboundTcpConnection.connect(OutboundTcpConnection.java:341)     at org.apache.cassandra.net.OutboundTcpConnection.run(OutboundTcpConnection.java:143) 

When going through know issues i found this The native library snappy-1.0.4.1-libsnappyjava.so for Snappy compression is included in the snappy-java-1.0.4.1.jar file. When the JVM initializes the JAR, the library is added to the default temp directory. If the default temp directory is mounted with a noexec option, it results in the above exception.

i added JVM_OPTS=-Dorg.xerial.snappy.tempdir=/tmp in cassandra.in.sh and it still didnot work. i also tried specifying the temp directory directly

./bin/cassandra -Dorg.xerial.snappy.tempdir=/tmp 

On the same machine cassandra version 1.0.12 works fine.

Any help will be appreciated.

The problem is that there is no FreeBSD library included in the snappy JAR file that comes with Cassandra. Install the archivers/snappy-java port, delete the snappy-java JAR file that came with Cassandra, and copy /usr/local/share/java/classes/snappy-java.jar into Cassandra's lib directory.

Same problem happened when trying to enable snappy compression for apache kafka 0.8 on FreeBSD but the solution was the same. Just copy /usr/local/share/java/classes/snappy-java.jar to the kafka/src/core/target/scala-2.8.0 directory, restart kafka and enjoy!
