Some changes have been made here. When executing addBlock(), some nodes will be excluded. These nodes include: 1. Non-locally activated DN node. 2. If xferport is greater than the length of datanodes. Below are some verified examples. step 1: There are some existing DN nodes, [hostname=hadoop1.jdhadoop.xxx.org, ip=xxxx.xxxx.xxxx.xxxx, xferport=50010] dn[hostname=hadoop2.jdhadoop.xxx.org, ip=xxxx.xxxx.xxxx.xxxx, xferport=50010] dn[hostname=hadoop3.jdhadoop.xxx.org, ip=xxxx.xxxx.xxxx.xxxx, xferport=50010] Step 2: Excuting an order. ./bin/hadoop org.apache.hadoop.hdfs.server.namenode.NNThroughputBenchmark -fs hdfs://xxxx -op blockReport -datanodes 3 Step 3: We will print some additional information. All surviving dn nodes: [hostname=hadoop1.jdhadoop.xxxx.org, ip=xxxx.xxxx.xxxx.xxxx xferport=1] dn[hostname=hadoop1.jdhadoop.xxxx.org, ip=xxxx, xferport=2] dn[hostname=hadoop1.jdhadoop.xxxx.org, ip=xxxx.xxxx.xxxx.xxxx.xxxx, xferport=3] dn[hostname=hadoop1.jdhadoop.xxxx.org, ip=xxx.xxx.xxx.xxx, xferport=50010] dn[hostname=hadoop2.jdhadoop.xxxx.org, ip=xxxx.xxx.xxx.xxx, xferport=50010] dn[hostname=hadoop3.jdhadoop.xxxx.org, ip=xxx.xxx.xxx.xxx.xxx, xferport=50010] The dn node that needs to be filtered: [hostname=hadoop1.jdhadoop.xxx.org, ip=xxx.xxx.xxx.xxx, xferport=50010] dn[hostname=hadoop2.jdhadoop.xxxx.org, ip=xxx.xxx.xxx.xxx, xferport=50010] dn[hostname=hadoop3.jdhadoop.xxx.org, ip=xxx.xxx.xxx.xxx, xferport=50010] Returned dn node: [hostname=hadoop1.jdhadoop.xxx.org, ip=xxxx.xxx.xxx.xxx, xferport=1],dn[hostname=hadoop1.jdhadoop.xxxx.org, ip=xxx.xxx.xxx .xxx, xferport=3] dn[hostname=hadoop1.jdhadoop.xxxx.org, ip=xxxx.xxx.xxx.xxx, xferport=2] @jojochuang, would you like to take some time to help review again.
