Hadoop 使用配置单元接收器将水槽输出保存到配置单元表

我正在尝试使用配置单元配置水槽，以使用配置单元接收器类型将水槽输出保存到配置单元表。我有单节点集群。我使用maprhadoop发行版

这是我的水槽

agent1.sources = source1
agent1.channels = channel1
agent1.sinks = sink1

agent1.sources.source1.type = exec
agent1.sources.source1.command = cat /home/andrey/flume_test.data

agent1.sinks.sink1.type = hive
agent1.sinks.sink1.channel = channel1
agent1.sinks.sink1.hive.metastore = thrift://127.0.0.1:9083
agent1.sinks.sink1.hive.database = default
agent1.sinks.sink1.hive.table = flume_test
agent1.sinks.sink1.useLocalTimeStamp = false
agent1.sinks.sink1.round = true
agent1.sinks.sink1.roundValue = 10
agent1.sinks.sink1.roundUnit = minute
agent1.sinks.sink1.serializer = DELIMITED
agent1.sinks.sink1.serializer.delimiter = "," 
agent1.sinks.sink1.serializer.serdeSeparator = ','
agent1.sinks.sink1.serializer.fieldnames = id,message

agent1.channels.channel1.type = FILE
agent1.channels.channel1.transactionCapacity = 1000000
agent1.channels.channel1.checkpointInterval 30000
agent1.channels.channel1.maxFileSize = 2146435071
agent1.channels.channel1.capacity 10000000
agent1.sources.source1.channels = channel1

我的数据水槽测试数据

这就是我在Hive中创建表格的方式

create table flume_test(id string, message string)
clustered by (message) into 1 buckets
STORED AS ORC tblproperties ("orc.compress"="NONE");

当我只使用1个bucket时，在hive shell中选择*from flume_test命令只返回OK状态，不返回数据。如果我使用超过1个bucket，它会返回错误消息

错误，例如在配置单元表选择之后有5个存储桶：

hive> select * from flume_test;
OK

配置单元表数据保存在/user/Hive/warehouse/flume\u test目录中，它不是空的

-rwxr-xr-x   3 andrey andrey          4 2015-06-17 16:28 /user/hive/warehouse/flume_test/_orc_acid_version
drwxr-xr-x   - andrey andrey          2 2015-06-17 16:28 /user/hive/warehouse/flume_test/delta_0004301_0004400

增量目录包含

-rw-r--r--   3 andrey andrey        991 2015-06-17 16:28 /user/hive/warehouse/flume_test/delta_0004301_0004400/bucket_00000

即使使用pig，我也无法读取/user/hive/warehouse/flume\u test/delta\u 0004301\u 0004400/bucket\u00000 orc文件

我还尝试在配置单元中创建表之后设置这个变量，但没有给出结果

set hive.txn.manager = org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;
set hive.compactor.initiator.on = true;
set hive.compactor.worker.threads = 2;

我在internet上发现了一些示例，但它们还没有满，而且我对flume还不熟悉，所以我无法理解它们）

将这两行添加到配置中解决了我的问题，但我在从hive读取表时仍然有错误。我可以读取该表，它返回正确的结果，但有错误

agent1.sinks.sink1.hive.txnsPerBatchAsk = 2
agent1.sinks.sink1.batchSize = 10

看起来您没有生成avsc文件。您似乎正在使用AVRO文件创建配置单元表，因此出现了错误
