Hbase寫Hfile報錯：Trying to load more than 32 hfiles to one family of one region

本文轉載自查看原文 2019-04-10 13:29 901 Hbase

在寫Hfile的時候，如果一個family下超過了默認的32個hfile，就會報如下錯誤：

ERROR mapreduce.LoadIncrementalHFiles: Trying to load more than 32 hfiles to family d of region with start key
Exception in thread "main" java.io.IOException: Trying to load more than 32 hfiles to one family of one region
        at org.apache.hadoop.hbase.mapreduce.LoadIncrementalHFiles.doBulkLoad(LoadIncrementalHFiles.java:288)
        at org.apache.hadoop.hbase.mapreduce.LoadIncrementalHFiles.run(LoadIncrementalHFiles.java:842)
        at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70)
        at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:84)
        at org.apache.hadoop.hbase.mapreduce.LoadIncrementalHFiles.main(LoadIncrementalHFiles.java:847)

解決：

在Hbase-site.xml中添加：

<property>
  　　　　<name>hbase.mapreduce.bulkload.max.hfiles.perRegion.perFamily</name>
  　　　　<value>3200</value>
  　　</property>
