我一直在尝试解决与snappy压缩相关的hbase的有线问题。以下是与此问题相关的所有内容的详细说明:
问题描述:当我尝试在hbase shell中使用snappy压缩创建表时:(有关调试模式下详细的hbase shell日志,请参阅附件)
hbase(main):001:0>创建't3',{name=>'cf1',compression=>'snappy'}

我设置了以下hbase-site.xml属性,hmaster和regionserver都可以正常启动和工作。
<property>
<name>hbase.regionserver.codecs</name>
<value>snappy</value>
</property>

有谁能帮忙解决这个问题吗?任何建议或线索将不胜感激!!
提前谢谢!!

snappy不适用于rhel操作系统,因为它依赖于rhel上不存在的其他库(clib),它适用于最新的linux操作系统。
