FuzzyRowFilter和IPC服务器无法读取调用参数:readFields出错

我正在尝试使用FuzzyRowFilter。我在Hbase 0.94.6-cdh4.3.0上,在Cloudera 4.3.0集群上。

在关注https://builds.apache.org/job/HBase-0.94/ws/trunk/src/main/java/org/apache/hadoop/hbase/filter/FuzzyRowFilter.java的链接后,我从https://issues.apache.org/jira/browse/HBASE-7628获得了java文件。我找不到 小版本766,所以从0.94 trunk中提取文件。

我有一个像这样扫描的测试表

HBase的(主):005:0>扫描'test_fuzzy_rules' ROW COLUMN + CELL
 1XX_2XX column = rules:rule1,timestamp = 1375719501754,value = rule1中的值
 1XX_2XX column = rules:rule2,timestamp = 1375719535698,value = rule2中的值
1行(0.0170秒*)。

我设置了如下所示的规则过滤器,并将其与Scan对象和HTable相关联。

FuzzyRowFilter fuzzyFilter = new FuzzyRowFilter( Arrays.asList(new Pair<byte[], byte[]>(Bytes.toBytesBinary("\\x00\\x00\\x00_2XX"), new byte[] {1, 1, 1, 0 , 0, 0, 0 })));

当我开始工作时,我收到以下错误

org.apache.hadoop.hbase.client.RetriesExhaustedException: Failed after attempts=10, exceptions:

知道这里发生了什么。我试图追踪错误但却迷失了。

由于 此致
