Question

HBase META.Region起动不成功怎么解决

Answer 1

在网上查看Region is not online: -ROOT-,,0相关的错误,也没有得到正确的答案,后来看了一下源码,报这个错误的地方是在:protected HRegion getRegion(final byte[] regionName)throws NotServingRegionException {HRegion region = null;region = getOnlineRegion(regionName);if (region == null) {throw new NotServingRegionException("Region is not online: " +Bytes.toStringBinary(regionName));}return region;}也就是说,regionName不再Map中,就会报这个错误,具体问题还得具体分析
