Hi Folks We are running hbase. We are using MultiRowRangeFilter in our java code for get the data for multi ranges. Below is snippet code: ranges.add(new RowRange(Bytes.toBytes(startRow), true, Bytes.toBytes(endRow), true));  Scan scan = new Scan();         MultiRowRangeFilter filter = new MultiRowRangeFilter(ranges);         FilterList filterList = new FilterList(FilterList.Operator.MUST_PASS_ALL);         filterList.addFilter(filter);         scan.setFilter(filterList);         scan.setCaching(500);  results = table.getScanner(scan); For specific table, we are getting null data, while same code is running for other tables. If i'm check checking manually by hbase shell, data is available. Even through single scan data is available using same code. How could i debug the data or query on Hbase level?

Hi, We are using HDP 3 in our environment. we are trying to load data from Local into using LOAD DATA LOCAL INPATH but we are getting error No path found.

Hi All, I'm trying to understand How hadoop 3 store data on HDFS by erasure encoding. As per erasure encoding, currently six built-in policies are supported: RS-3-2-1024k,RS-6-3-1024k, RS-10-4-1024k, RS-LEGACY-6-3-1024k, XOR-2-1-1024k and REPLICATION. Replication is general term which was also using in hadoop2(replicate the data 3x). How Reed Solomony RS-3-2-1024k(3 data blocks, 2 parity blocks and 1024k cell size) or RS-6-3-1-24k(6 data blocks, 3 parity blocks and 1024k cell size) store the data? Suppose we are having 3 data nodes, 2 NNs, 1 Edge node. We have to store the 1GB file(abc.txt) and Block size is 128MB. How RS-3-2-1024k, RS-6-3-1024k works? What is meaning of 6 data blocks, 1024K? Is there any specific prerequisites for number of DATANODE's required, according to policy? Will appreciable in advance to help me to understand the hadoop 3 concept. Regards, Vinay K ... View more
