Therefore, users can inadvertently > configure an invalid class name and it will be recorded into the WAL file. > At that point, the WAL file becomes unreadable and blocks processing of all > other WAL files. > {code:java|title=AbstractProtobufLogWriter.java} > private WALHeader buildWALHeader0(Configuration conf, WALHeader.Builder > builder) { > if (!builder.hasWriterClsName()) { > builder.setWriterClsName(getWriterClassName()); > } > if (!builder.hasCellCodecClsName()) { > builder.setCellCodecClsName(WALCellCodec.getWALCellCodecClass(conf)); > } > return builder.build(); > } > {code} > https://github.com/apache/hbase/blob/025ddce868eb06b4072b5152c5ffae5a01e7ae30/hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/wal/AbstractProtobufLogWriter.java#L78-L86 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
