Here is an example
from
phoenix-core/src/main/java/org/apache/phoenix/coprocessor/MetaDataEndpointImpl.java
:
byte[] suffix =
ByteUtil.concat(QueryConstants.SEPARATOR_BYTE_ARRAY,
SchemaUtil.getTableNameAsBytes(schemaName, tableName));
SuffixFilter rowFilter = new SuffixFilter(suffix);
Filter filter = new FilterList(linkFilter, rowFilter);
You can use the following method from Bytes.java (in hbase-common) to
obtain byte[] from "12345"
public static byte[] toBytes(String s) {
