org.apache.hadoop.io.compress.SnappyCodec not found
Hi, I use Hadoop 2.4.1 and HBase 0.98.5 with snappy enabled in both Hadoop and HBase. With default setting in Spark 1.0.2, when trying to load a file I got Class org.apache.hadoop.io.compress.SnappyCodec not found Can you please advise how to enable snappy in Spark?

Also, if you are using 64 bit system, remember to re-compile the snappy native library to 64-bit, cause the official snappy lib is 32-bit. $ file /usr/lib/hadoop/lib/native/*/usr/lib/hadoop/lib/native/libhadoop.a: current ar archive/usr/lib/hadoop/lib/native/libhadooppipes.a: current ar archive/usr/lib/hadoop/lib/native/libhadoop.so: symbolic link to `libhadoop.so.1.0.0'/usr/lib/hadoop/lib/native/libhadoop.so.1.0.0: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped/usr/lib/hadoop/lib/native/libhadooputils.a: current ar archive/usr/lib/hadoop/lib/native/libhdfs.a: current ar archive/usr/lib/hadoop/lib/native/libsnappy.so: symbolic link to `libsnappy.so.1.1.3'/usr/lib/hadoop/lib/native/libsnappy.so.1: symbolic link to `libsnappy.so.1.1.3'/usr/lib/hadoop/lib/native/libsnappy.so.1.1.3: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped BRs,Patrick Liu Date: Thu, 28 Aug 2014 18:36:25 -0700 From: ml-node+s1001560n13084...@n3.nabble.com To: linkpatrick...@live.com Subject: Re: org.apache.hadoop.io.compress.SnappyCodec not found Hi, I fixed the issue by copying libsnappy.so to Java ire.
