java - DateType column metadata column in Cassandra database -

-

i working cassandra database. have created below column family

create column family user comparator = 'utf8type' , default_validation_class = 'utf8type' , column_metadata = [                 {column_name : account, validation_class : 'utf8type'}                 {column_name : lmd, validation_class : 'datetype'}  ];

now trying insert cassandra database using pelops client

mutator.writecolumns(column_family, string.valueof(userid),                         mutator.newcolumnlist(                         mutator.newcolumn("account", "hello"),                          mutator.newcolumn("lmd", string.valueof(new date().gettime()))                                       ));

in case, created lmd datetype in column family not sure how add datetype through code. adding string need make sure compatible datetype.

can me this?

well, have created column family using cli. try using these

set user['somekey']['account']='ac-46113'; set user['somekey']['lmd']=1365490146534; list user;

now have same thing using pelops 

mutator.writecolumns(column_family, string.valueof(userid),                     mutator.newcolumnlist(                     mutator.newcolumn("account", "hello"),                      mutator.newcolumn("lmd", bytes.fromlong(system.currenttimemillis()))                                   ));

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
