Description
When I use
hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot "wh_scan_issue_monitor_on_snap_1" -copy-from hdfs://xxxx:8020/hbase -copy-to hdfs://xxx:8020/hbase
to copy snapshot from hbase2.0.0 to hbase 1.2.0 and then use
clone_snapshot 'wh_scan_issue_monitor_on_snap_1',"wh_scan_issue_monitor_table"
to restore the table;
There are no errors on client and hbase master.
but I can not scan any data in this new table.
So when I search the log in regionserver which that region running on .I find the below error log
2018-11-29 13:39:45,826 ERROR org.apache.hadoop.hbase.regionserver.StoreFile$Reader: Error reading bloom filter meta for GENERAL_BLOOM_META -- proceeding without java.io.IOException: java.lang.ClassNotFoundException: at org.apache.hadoop.hbase.io.hfile.FixedFileTrailer.getComparatorClass(FixedFileTrailer.java:581) at org.apache.hadoop.hbase.io.hfile.FixedFileTrailer.createComparator(FixedFileTrailer.java:588) at org.apache.hadoop.hbase.util.CompoundBloomFilter.<init>(CompoundBloomFilter.java:73) at org.apache.hadoop.hbase.util.BloomFilterFactory.createFromMeta(BloomFilterFactory.java:109) at org.apache.hadoop.hbase.regionserver.StoreFile$Reader.loadBloomfilter(StoreFile.java:1469) at org.apache.hadoop.hbase.regionserver.StoreFile$Reader.access$000(StoreFile.java:1088) at org.apache.hadoop.hbase.regionserver.StoreFile.open(StoreFile.java:465) at org.apache.hadoop.hbase.regionserver.StoreFile.createReader(StoreFile.java:509) at org.apache.hadoop.hbase.regionserver.StoreFile.createReader(StoreFile.java:499) at org.apache.hadoop.hbase.regionserver.HStore.createStoreFileAndReader(HStore.java:676) at org.apache.hadoop.hbase.regionserver.HStore.access$000(HStore.java:119) at org.apache.hadoop.hbase.regionserver.HStore$1.call(HStore.java:543) at org.apache.hadoop.hbase.regionserver.HStore$1.call(HStore.java:540) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.ClassNotFoundException: at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:264) at org.apache.hadoop.hbase.io.hfile.FixedFileTrailer.getComparatorClass(FixedFileTrailer.java:578) ... 18 more
