使用Snappy压缩的HBase表中的BulkLoad获取UnsatisfiedLinkError

Question

当尝试从M/R批量加载到启用了Snappy压缩的表中时。我得到以下错误：

ERROR mapreduce.LoadIncrementalHFiles: Unexpected execution exception during splitting 
java.util.concurrent.ExecutionException: java.lang.UnsatisfiedLinkError: org.apache.hadoop.util.NativeCodeLoader.buildSupportsSnappy()Z 
at java.util.concurrent.FutureTask$Sync.innerGet(FutureTask.java:252) 
    at java.util.concurrent.FutureTask.get(FutureTask.java:111) 
    at org.apache.hadoop.hbase.mapreduce.LoadIncrementalHFiles.groupOrSplitPhase(LoadIncrementalHFiles.java:335) 
    at org.apache.hadoop.hbase.mapreduce.LoadIncrementalHFiles.doBulkLoad(LoadIncrementalHFiles.java:234) 

表的描述是：

DESCRIPTION                             ENABLED                
{NAME => 'matrix_com', FAMILIES => [{NAME => 't', BLOOMFILTER => 'NONE', REPLICATION_SCOPE => '0', COMPRESSION => 'SNAPPY' true                 
, VERSIONS => '12', TTL => '1555200000', MIN_VERSIONS => '0', BLOCKSIZE => '65536', IN_MEMORY => 'false', BLOCKCACHE => 't                  
rue'}]} 

如果Hadoop的已安装所有活泼的编解码器，也HBase的不给人以活泼的创建表时的错误，我为什么我得到这个错误？

看来这是一个刚刚由Hadoop开发人员修复的错误。请检查以下链接 https://issues.apache.org/jira/browse/MAPREDUCE-5799
