dfs.namenode.name.dir file:///c:/hadoop/hdpdatann/nn Determines where on the local filesystem the DFS name node should store the name table. If this is a comma-delimited list of directories then the name table is replicated in all of the directories, for redundancy. true dfs.support.append true to enable dfs append true dfs.webhdfs.enabled true to enable webhdfs true dfs.datanode.failed.volumes.tolerated 0 #of failed disks dn would tolerate true dfs.datanode.data.dir file:///c:/hadoop/hdpdatadn/dn Determines where on the local filesystem an DFS data node should store its blocks. If this is a comma-delimited list of directories, then data will be stored in all named directories, typically on different devices. Directories that do not exist are ignored. true dfs.checksum.type CRC32 The checksum method to be used by default. To maintain compatibility, it is being set to CRC32. Once all migration steps are complete, we can change it to CRC32C and take advantage of the additional performance benefit. dfs.replication.max 50 Maximal block replication. dfs.heartbeat.interval 3 Determines datanode heartbeat interval in seconds. dfs.namenode.safemode.threshold-pct 1.0f Specifies the percentage of blocks that should satisfy the minimal replication requirement defined by dfs.replication.min. Values less than or equal to 0 mean not to start in safe mode. Values greater than 1 will make safe mode permanent. dfs.datanode.balance.bandwidthPerSec 6250000 Specifies the maximum amount of bandwidth that each datanode can utilize for the balancing purpose in term of the number of bytes per second. dfs.datanode.address 0.0.0.0:50010 dfs.datanode.http.address 0.0.0.0:50075 dfs.datanode.https.address 0.0.0.0:50076 dfs.blocksize 134217728 The default block size for new files, in bytes. You can use the following suffix (case insensitive): k(kilo), m(mega), g(giga), t(tera), p(peta), e(exa) to specify the size (such as 128k, 512m, 1g, etc.), Or provide complete size in bytes (such as 134217728 for 128 MB). dfs.namenode.http-address cc-wvd-ap161.pepcoholdings.biz:50070 The address and the base port where the dfs namenode web ui will listen on. If the port is 0 then the server will start on a free port. true dfs.https.port 50070 true dfs.datanode.du.reserved 1073741824 Reserved space in bytes per volume. Always leave this much space free for non dfs use. dfs.datanode.ipc.address 0.0.0.0:8010 The datanode ipc server address and port. If the port is 0 then the server will start on a free port. dfs.blockreport.initialDelay 120 Delay for first block report in seconds. dfs.datanode.du.pct 0.85f When calculating remaining space, only use this percentage of the real available space dfs.namenode.handler.count 40 The number of server threads for the namenode. dfs.namenode.checkpoint.dir file:///c:/hadoop/hdpdatann/snn Determines where on the local filesystem the DFS secondary name node should store the temporary images to merge. If this is a comma-delimited list of directories then the image is replicated in all of the directories for redundancy. dfs.namenode.checkpoint.edits.dir file:///c:/hadoop/hdpdatann/snn Determines where on the local filesystem the DFS secondary name node should store the temporary edits to merge. If this is a comma-delimited list of directoires then teh edits is replicated in all of the directoires for redundancy. Default value is same as dfs.namenode.checkpoint.dir dfs.namenode.checkpoint.period 86400 The number of seconds between two periodic checkpoints. dfs.datanode.max.transfer.threads 1024 Specifies the maximum number of threads to use for transferring data in and out of the DN. dfs.permissions.enabled true If "true", enable permission checking in HDFS. If "false", permission checking is turned off, but all other behavior is unchanged. Switching from one parameter value to the other does not change the mode, owner or group of files or directories. dfs.permissions.superusergroup hdfs The name of the group of super-users. ipc.server.max.response.size 5242880 dfs.block.access.token.enable false If "true", access tokens are used as capabilities for accessing datanodes. If "false", no access tokens are checked on accessing datanodes. dfs.namenode.secondary.http-address cc-wvd-ap161a.pepcoholdings.biz:50090 Address of secondary namenode web server dfs.secondary.https.port 50091 The https port where secondary-namenode binds dfs.namenode.https-address cc-wvd-ap161.pepcoholdings.biz:50701 The https address where namenode binds dfs.datanode.data.dir.perm 755 The permissions that should be there on dfs.data.dir directories. The datanode will not come up if the permissions are different on existing dfs.data.dir directories. If the directories don't exist, they will be created with this permission. dfs.namenode.accesstime.precision 0 The access time for HDFS file is precise upto this value. The default value is 1 hour. Setting a value of 0 disables access times for HDFS. dfs.cluster.administrators hdfs ACL for who all can view the default servlets in the HDFS ipc.server.read.threadpool.size 5 dfs.encrypt.data.transfer false dfs.encrypt.data.transfer.algorithm 3des dfs.https.enable false dfs.replication 1 dfs.hosts.exclude c:\hadoop\hdp\hadoop-2.7.1.2.4.0.0-169\etc\hadoop\dfs.exclude dfs.hosts c:\hadoop\hdp\hadoop-2.7.1.2.4.0.0-169\etc\hadoop\dfs.include
