通过知道的问题，我发现这个
本地库Snappy-1.0.4.1-libsnappyjava.so Snappy压缩包括在snappy-java-1.0.4.1.jar文件中。当JVM初始化JAR时，库将添加到默认临时目录。如果使用noexec选项装载默认临时目录，则会导致上述异常。
When going through know issues i found thisThe 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.
我添加了JVM_OPTS = -Dorg.xerial.snappy.tempdir = / tmp cassandra.in.sh，它仍然没有工作。
i也尝试直接指定临时目录
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
在同一台机器上Cassandra版本1.0.12工作正常。
On the same machine cassandra version 1.0.12 works fine.
任何帮助将不胜感激。
推荐答案
问题是，没有FreeBSD库包含在Cassandra附带的snappy JAR文件中。安装archivers / snappy-java端口，删除Cassandra附带的snappy-java JAR文件，并将/usr/local/share/java/classes/snappy-java.jar复制到Cassandra的lib目录中。
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.
