问flume中failover自动切换sink失败？

由于使用的是HA，两个namenode会不定时休眠其中一个，为了从业务主机上采集的数据不丢失，配置了两个sink，但是无法自动切换，配置文件如下：

a00.sources = r00

a00.sinks = k00_1 k00_2

a00.channels = c00

# Describe/configure the source

a00.sources.r00.type = exec

a00.sources.r00.command = tail -F /home/flume/others/test/20190419_test/apvtest.log

a00.sources.r00.channels = c00

#set gruop

a00.sinkgroups = g00

a00.sinkgroups.g00.sinks = k00_1 k00_2

#set failove

a00.sinkgroups.g00.processor.type = failove

a00.sinkgroups.g00.processor.priority.k00_1 = 10

a00.sinkgroups.g00.processor.priority.k00_2 = 5

#最长等待10秒转移故障20190416

a00.sinkgroups.g00.processor.maxpenalty = 10000

# set sink1

a00.sinks.k00_1.type = hdfs

a00.sinks.k00_1.hdfs.path = hdfs://***.***.***.157:9000/flume/log-test/%Y%m%d

a00.sinks.k00_1.hdfs.filePrefix = apv3

a00.sinks.k00_1.hdfs.fileSuffix = .log

a00.sinks.k00_1.hdfs.batchSize= 500

a00.sinks.k00_1.hdfs.fileType = DataStream

a00.sinks.k00_1.hdfs.writeFormat =Text

a00.sinks.k00_1.hdfs.rollSize = 0

a00.sinks.k00_1.hdfs.rollCount = 0

a00.sinks.k00_1.hdfs.rollInterval = 100

a00.sinks.k00_1.hdfs.round = true

a00.sinks.k00_1.hdfs.roundValue = 24

a00.sinks.k00_1.hdfs.roundUnit = houre

a00.sinks.k00_1.hdfs.useLocalTimeStamp = true

# set sink2

a00.sinks.k00_2.type = hdfs

a00.sinks.k00_2.hdfs.path = hdfs://***.***.***.165:9000/flume/log-test/%Y%m%d

a00.sinks.k00_2.hdfs.filePrefix = apv3

a00.sinks.k00_2.hdfs.fileSuffix = .log

a00.sinks.k00_2.hdfs.batchSize= 500

a00.sinks.k00_2.hdfs.fileType = DataStream

a00.sinks.k00_2.hdfs.writeFormat =Text

a00.sinks.k00_2.hdfs.rollSize = 0

a00.sinks.k00_2.hdfs.rollCount = 0

a00.sinks.k00_2.hdfs.rollInterval = 100

a00.sinks.k00_2.hdfs.round = true

a00.sinks.k00_2.hdfs.roundValue = 24

a00.sinks.k00_2.hdfs.roundUnit = houre

a00.sinks.k00_2.hdfs.useLocalTimeStamp = true

# Use a channel which buffers events in memory

a00.channels.c00.type = memory

a00.channels.c00.capacity = 50000

a00.channels.c00.transactionCapacity = 6000

# Bind the source and sink to the channel

a00.sinks.k00_1.channel = c00

a00.sinks.k00_2.channel = c00

。但是当157的节点休眠时，还是不能采集数据，日志中一直报错，节点休眠.......请问如何解决？
