HBase性能测试

 

 

HBase PerformanceEvaluation：

 

Options:
 nomapred        Run multiple clients using threads (rather than use mapreduce)
 rows            Rows each client runs. Default: One million
 size            Total size in GiB. Mutually exclusive with --rows. Default: 1.0.
 sampleRate      Execute test on a sample of total rows. Only supported by randomRead. Default: 1.0
 traceRate       Enable HTrace spans. Initiate tracing every N rows. Default: 0
 table           Alternate table name. Default: 'TestTable'
 multiGet        If >0, when doing RandomRead, perform multiple gets instead of single gets. Default: 0
 compress        Compression type to use (GZ, LZO, ...). Default: 'NONE'
 flushCommits    Used to determine if the test should flush the table. Default: false
 writeToWAL      Set writeToWAL on puts. Default: True
 autoFlush       Set autoFlush on htable. Default: False
 oneCon          all the threads share the same connection. Default: False
 presplit        Create presplit table. Recommended for accurate perf analysis (see guide).  Default: disabled
 inmemory        Tries to keep the HFiles of the CF inmemory as far as possible. Not guaranteed that reads are always served from memory.  Default: false
 usetags         Writes tags along with KVs. Use with HFile V3. Default: false
 numoftags       Specify the no of tags that would be needed. This works only if usetags is true.
 filterAll       Helps to filter out all the rows on the server side there by not returning any thing back to the client. 
 latency         Set to report operation latencies. Default: False
 bloomFilter      Bloom filter type, one of [NONE, ROW, ROWCOL]
 valueSize       Pass value size to use: Default: 1024
 valueRandom     Set if we should vary value size between 0 and 'valueSize'; set on read for stats on size: Default: Not set.
 valueZipf       Set if we should vary value size between 0 and 'valueSize' in zipf form: Default: Not set.
 period          Report every 'period' rows: Default: opts.perClientRunRows / 10
 multiGet        Batch gets together into groups of N. Only supported by randomRead. Default: disabled
 addColumns      Adds columns to scans/gets explicitly. Default: true
 replicas        Enable region replica testing. Defaults: 1.
 splitPolicy     Specify a custom RegionSplitPolicy for the table.
 randomSleep     Do a random sleep before each get between 0 and entered value. Defaults: 0
 columns         Columns to write per row. Default: 1
 caching         Scan caching to use. Default: 30

 Note: -D properties will be applied to the conf used. 
  For example: 
   -Dmapreduce.output.fileoutputformat.compress=true
   -Dmapreduce.task.timeout=60000

Command:
 filterScan      Run scan test using a filter to find a specific row based on it's value (make sure to use --rows=20)
 randomRead      Run random read test
 randomSeekScan  Run random seek and scan 100 test
 randomWrite     Run random write test
 scan            Run scan test (read every row)
 scanRange10     Run random seek scan with both start and stop row (max 10 rows)
 scanRange100    Run random seek scan with both start and stop row (max 100 rows)
 scanRange1000   Run random seek scan with both start and stop row (max 1000 rows)
 scanRange10000  Run random seek scan with both start and stop row (max 10000 rows)
 sequentialRead  Run sequential read test
 sequentialWrite Run sequential write test

Args:
 nclients        Integer. Required. Total number of clients (and HRegionServers)
                 running: 1 <= value <= 500
