Suresh Srinivas updated HDFS-3735:
----------------------------------
Description:
Live datanode list is not correctly sorted for columns Block Pool Used (GB),
Block Pool Used (%) and Failed Volumes. Read comments for more details.
was:
*Fields which will display on dfsnodelist.jsp?whatNodes=LIVE ( NNUI->click on
live nodes)*
Node| Last-contact |Admin State| Configured Capacity(GB)|Used(GB)|
Non DFSUsed(GB)Remaining(GB)|Used(%)|Used(%)|Remaining(%)|Blocks|
Block Pool Used (GB)|Block Pool Used (%)> Blocks|Failed Volumes H *-->*
{color:red}these three fields not considered for sorting{color}
we can display data in sorting order by clicking on the anyone of above
fields.It's working fine for all fields expect last three fields.
*code where we are considering fileds.*
{code}
class NodeComapare implements Comparator<DatanodeDescriptor> {
static final int
FIELD_NAME = 1,
FIELD_LAST_CONTACT = 2,
FIELD_BLOCKS = 3,
FIELD_CAPACITY = 4,
FIELD_USED = 5,
FIELD_PERCENT_USED = 6,
FIELD_NONDFS_USED = 7,
FIELD_REMAINING = 8,
FIELD_PERCENT_REMAINING = 9,
FIELD_ADMIN_STATE = 10,
FIELD_DECOMMISSIONED = 11,
SORT_ORDER_ASC = 1,
SORT_ORDER_DSC = 2;
{code}
Here,last three fields we are not considering..hence it's assign default filed.
{code}
} else if (field.equals("blocks")) {
sortField = FIELD_BLOCKS;
} else if (field.equals("adminstate")) {
sortField = FIELD_ADMIN_STATE;
} else if (field.equals("decommissioned")) {
sortField = FIELD_DECOMMISSIONED;
} else {
sortField = FIELD_NAME;
}
{code}
Please correct me ,If I am wrong...
