为了验证存在不同的hdfs之间的hive的互操作（归根结底还是为了解决BUG）

需要在两个不同的hadoop集群的HDFS  能够在Hiveserver2上进行路由转发绕过一些坑。

就需要将某hdfs集群的配置文件改改。。

例如hdfs-site.xml

EG：

dfs.nameservices sfbd,sfbdp1,oldsfbdp1,oldsfbd       dfs.ha.namenodes.sfbd nn1,nn2 dfs.namenode.rpc-address.sfbd.nn1 CNSZ17PL1782:8020 dfs.namenode.rpc-address.sfbd.nn2 CNSZ17PL1783:8020 dfs.namenode.http-address.sfbd.nn1 CNSZ17PL1782:50070 dfs.namenode.http-address.sfbd.nn2 CNSZ17PL1783:50070 dfs.client.failover.proxy.provider.sfbd org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider dfs.namenode.shared.edits.dir.sfbd qjournal://CNSZ17PL1786:8485;CNSZ17PL1787:8485;CNSZ17PL1788:8485;CNSZ17PL1789:8485;CNSZ17PL1790:8485/sfbd dfs.ha.namenodes.sfbdp1 nn1,nn2 dfs.namenode.rpc-address.sfbdp1.nn1 CNSZ17PL1784:8020 dfs.namenode.rpc-address.sfbdp1.nn2 CNSZ17PL1785:8020 dfs.namenode.http-address.sfbdp1.nn1 CNSZ17PL1784:50070 dfs.namenode.http-address.sfbdp1.nn2 CNSZ17PL1785:50070 dfs.client.failover.proxy.provider.sfbdp1 org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider dfs.namenode.shared.edits.dir.sfbdp1 qjournal://CNSZ17PL1786:8485;CNSZ17PL1787:8485;CNSZ17PL1788:8485;CNSZ17PL1789:8485;CNSZ17PL1790:8485/sfbdp1 dfs.client.failover.proxy.provider.oldsfbdp1 org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider dfs.ha.namenodes.oldsfbdp1 namenode313,namenode411 dfs.namenode.rpc-address.oldsfbdp1.namenode313 cnsz17pl1206:8020 dfs.namenode.http-address.oldsfbdp1.namenode313 cnsz17pl1206:50070 dfs.namenode.rpc-address.oldsfbdp1.namenode411 cnsz17pl1207:8020 dfs.namenode.http-address.oldsfbdp1.namenode411 cnsz17pl1207:50070 dfs.ha.namenodes.oldsfbd nn1,nn2 dfs.namenode.rpc-address.oldsfbd.nn1 cnsz23pl0090:8020 dfs.namenode.rpc-address.oldsfbd.nn2 cnsz23pl0091:8020 dfs.namenode.http-address.oldsfbd.nn1 cnsz23pl0090:50070 dfs.namenode.http-address.oldsfbd.nn2 cnsz23pl0091:50070 dfs.client.failover.proxy.provider.oldsfbd org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider dfs.namenode.name.dir file:///data/dfs/nn/local dfs.datanode.data.dir /HDATA/12/dfs/local,/HDATA/11/dfs/local,/HDATA/10/dfs/local,/HDATA/9/dfs/local,/HDATA/8/dfs/local,/HDATA/7/dfs/local,/HDATA/6/dfs/local,/HDATA/5/dfs/local,/HDATA/4/dfs/local,/HDATA/3/dfs/local,/HDATA/2/dfs/local,/HDATA/1/dfs/local dfs.journalnode.edits.dir /data/dfs/jn dfs.qjournal.start-segment.timeout.ms 60000 dfs.qjournal.prepare-recovery.timeout.ms 240000 dfs.qjournal.accept-recovery.timeout.ms 240000 dfs.qjournal.finalize-segment.timeout.ms 240000 dfs.qjournal.select-input-streams.timeout.ms 60000 dfs.qjournal.get-journal-state.timeout.ms 240000 dfs.qjournal.new-epoch.timeout.ms 240000 dfs.qjournal.write-txns.timeout.ms 60000 dfs.namenode.acls.enabled true Number of replication for each chunk. dfs.ha.fencing.methods sshfence dfs.ha.fencing.ssh.private-key-files /home/hdfs/.ssh/id\_rsa dfs.ha.automatic-failover.enabled true dfs.permissions.superusergroup hadoop dfs.datanode.max.transfer.threads 8192 dfs.hosts.exclude /app/hadoop-conf/exclude.list List of nodes to decommission dfs.datanode.fsdataset.volume.choosing.policy org.apache.hadoop.hdfs.server.datanode.fsdataset.AvailableSpaceVolumeChoosingPolicy dfs.datanode.available-space-volume-choosing-policy.balanced-space-threshold 10737418240 dfs.datanode.available-space-volume-choosing-policy.balanced-space-preference-fraction 0.75 dfs.client.read.shortcircuit.streams.cache.size 1000 dfs.client.read.shortcircuit.streams.cache.expiry.ms 10000 dfs.client.read.shortcircuit true dfs.domain.socket.path /app/var/run/hadoop-hdfs/dn.\_PORT dfs.client.read.shortcircuit.skip.checksum false dfs.block.size 134217728 dfs.replication 3 dfs.namenode.handler.count 300 dfs.datanode.handler.count 40 dfs.webhdfs.enabled true dfs.namenode.datanode.registration.ip-hostname-check false
